INTRODUCTION: Carcinosarcomas are malignant biphasic tumours of epithelial and mesenchymal tissue. They are most often found in visceral organs, but also appear on the skin. Older age, male sex and chronic sun exposure are risk factors for its development. In this article we report a case and provide a review of literature regarding primary cutaneous carcinosarcoma (CCS) with special regard to its management. MATERIAL AND METHODS: A manual electronic search of the PubMed Medline and Web of Science Core Collection databases was performed encompassing all included reports until 30th November 2022 to identify studies that reported primary CCS. RESULTS: CCS is a rare and aggressive tumour. Diagnosis requires histological examination and immunoreactivity of epithelial and mesenchymal components to specific markers. On its diagnosis, possibility of metastasis of a visceral carcinosarcoma should always be excluded. Surgical excision with clear margins, including the use of Mohs micrographic surgery (MMS), is the primary treatment for CCS. Reconstruction the excision defect should be performed. Regular follow-up for 5 to 10 years after initial treatment is advised. CONCLUSION: Awareness for CCS is necessary in the diagnostic evaluation of skin tumours. Further research is needed to better understand the underlying mechanisms of CCS and to establish optimal management strategies for this challenging malignancy. We recommend complete surgical excision using MMS as the treatment modality for this type of skin cancer. Dermatological follow-up for at least 5 years should be conducted to monitor for recurrence.

OBJECTIVE: To describe the clinical and ultrasound characteristics of ovarian carcinosarcoma. METHODS: This was a retrospective multicenter study. Patients with a histological diagnosis of ovarian carcinosarcoma, who had undergone preoperative ultrasound examination between 2010 and 2019, were identified from the International Ovarian Tumor Analysis (IOTA) database. Additional patients who were examined outside of the IOTA study were identified from the databases of the participating centers. The masses were described using the terms and definitions of the IOTA group. Additionally, two experienced ultrasound examiners reviewed all available images to identify typical ultrasound features using pattern recognition. RESULTS: Ninety-one patients with ovarian carcinosarcoma who had undergone ultrasound examination were identified, of whom 24 were examined within the IOTA studies and 67 were examined outside of the IOTA studies. Median age at diagnosis was 66 (range, 33-91) years and 84/91 (92.3%) patients were postmenopausal. Most patients (67/91, 73.6%) were symptomatic, with the most common complaint being pain (51/91, 56.0%). Most tumors (67/91, 73.6%) were International Federation of Gynecology and Obstetrics (FIGO) Stage III or IV. Bilateral lesions were observed on ultrasound in 46/91 (50.5%) patients. Ascites was present in 38/91 (41.8%) patients. The median largest tumor diameter was 100 (range, 18-260) mm. All ovarian carcinosarcomas contained solid components, and most were described as solid (66/91, 72.5%) or multilocular-solid (22/91, 24.2%). The median diameter of the largest solid component was 77.5 (range, 11-238) mm. Moderate or rich vascularization was found in 78/91 (85.7%) cases. Retrospective analysis of ultrasound images and videoclips using pattern recognition in 73 cases revealed that all tumors had irregular margins and inhomogeneous echogenicity of the solid components. Forty-seven of 73 (64.4%) masses appeared as a solid tumor with cystic areas. Cooked appearance of the solid tissue was identified in 28/73 (38.4%) tumors. No pathognomonic ultrasound sign of ovarian carcinosarcoma was found. CONCLUSIONS: Ovarian carcinosarcomas are usually diagnosed in postmenopausal women and at an advanced stage. The most common ultrasound appearance is a large solid tumor with irregular margins, inhomogeneous echogenicity of the solid tissue and cystic areas. The second most common pattern is a large multilocular-solid mass with inhomogeneous echogenicity of the solid tissue. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

BACKGROUND: Squamous cell carcinoma is the most common malignant tumor of the uterine cervix with a well-documented link to infection with human papillomaviruses (HPV). According to a recent classification, there are several morphological variants of cervical squamous carcinoma, without reference to sarcomatoid squamous cell carcinoma, which is well described in other organs. CASE PRESENTATION: In this paper, we describe an extremely rare case of a 77-year-old woman with primary malignant cervical tumor displaying biphasic histomorphology with an epithelioid and sarcomatoid part; the latter was immunohistochemistry positive for cytokeratin and vimentin. The association with a high-grade squamous intraepithelial lesion and molecular proof of HPV33 infection in the tumor tissue supported our diagnosis of carcinoma with partial sarcomatoid differentiation. CONCLUSION: We report a rare case of a primary cervical epithelial tumor with a partial sarcomatoid phenotype, an unequivocal HPV infection, and an associated precancerous lesion in the cervical mucosa. This is the first description of an HPV33 infection underlying a biphasic epithelioid-sarcomatous tumor of the uterine cervix. The terminology overlap between sarcomatoid carcinoma and carcinosarcoma is also discussed.

OBJECTIVE: The case report presents a case of 60-year old woman with a rare malignant mixed Müllerian tumor with melanomatous differentiation diagnosed from a histology after cervical polyp ablation and curettage. DESIGN: Case report. SETTING: Department of gynecology and obstetrics, University Hospital in Pilsen. CONCLUSION: Carcinosarcoma, previously malignant mixed Müllerian tumor, is a very rare aggressive endometrial carcinoma with low incidence, which typically occurs among older women and commonly affects the uterine body and cervix. Clinically, the carcinosarcoma is impossible to be distinguished from endometrial carcinoma or uterine sarcoma and the definitive diagnosis can only be made based on histological examination.

OBJECTIVE: Analysis of clinical and histopathological prognostic factors with emphasis on carcinosarcomas, leiomyosarcomas and endometrial sarcomas of uterus. SUBJECT: Review. SETTING: Department of Obstetrics and Gynaecology, Medical Faculty Hradec Králové, Charles University, Prague; The Fingerland Department of Pathology, Medical Faculty Hradec Králové, Charles University, Prague; Department of Clinical Oncology, Medical Faculty Hradec Králové, Charles University, Prague; Department of Biological and Medical Sciences, Faculty of Pharmacy, Hradec Králové; Charles University, Prague. SUBJECT AND METHOD: Discussion about our experience and current evidence. CONCLUSION: Mesenchymal and mixed tumors of uterus are characterized by several prognostic factors as well. Except clinical prognostic variables, histopathological and molecular biological factors may play a role. The most important prognostic significance carry stage of disease, age and performance status of patient and sufficient therapy, especially surgery. In particular tumors some other prognostic factors are recognized. Except cases in really early stage of disease there is usually short interval between end of primary therapy and tumor recurrence. With the exception of endometrial stromal sarcoma, prognosis of these tumors remains very poor.

A case of low-grade trichoblastic carcinosarcoma was reported in 2004. Here we present the second case of this tumor, which, in contrast to the original example, may be classified as a high-grade neoplasm. A 92-year-old man presented with an ulcerated lesion on the left ear. The tumor was excised, and the patient had no evidence of recurrence or metastasis 6 years after surgery. Microscopically, the neoplasm demonstrated a fenestrated growth pattern with a slightly myxoid matrix in the background. Two clear components were identified: the first component was clearly epithelial with formation of small round nests, lobules, delicate strands, and small cribriform structures of basaloid cells with some degree of peripheral palisading, nuclear atypia, focal nuclear crowding, and frequent mitotic figures including abnormal forms. Each epithelial aggregation was invariably surrounded by one to three rows of cells with oval to round nuclei, which appeared very similar to specific trichogenic stroma seen in anagen follicles or in trichoblastomas; however, these stromal cells manifested atypical mitoses and cellular pleomorphism. The epithelial and stromal units frequently formed structures identical to follicular papillae associated with germs or "continuous germs" contiguous with "continuous papillae." Despite the close association throughout the tumor, the epithelial and the stromal cells were sharply separated, without transition between both elements. In foci, these stromal cells lost their follicular papillae-like arrangement and proliferated in a diffuse fashion and gradually blended with highly pleomorphic mononuclear spindle-shaped cells and bizarre multinucleated cells that grew in sheets in a highly vascular stroma. Immunohistochemically, the epithelial component showed diffuse staining for cytokeratins (AE1/AE3) and was negative for vimentin and CAM5.2. The stromal cells were positive for vimentin and negative for cytokeratin markers (AE1/AE3) and desmin. We view the present case and that previously reported in 2004 as authentic carcinosarcomas, and not as metaplastic (sarcomatoid) basal cell carcinomas. This conclusion is reached after analyzing the embryological development of the hair follicle, its normal histology and the morphology of cutaneous adnexal tumors with follicular differentiation.

An unusual low-grade metaplastic carcinoma (müllerian carcinosarcoma) of the uterine corpus occurring in a 45-year-old woman is presented. The tumor was polypoid and showed an initial invasion into the myometrium. The epithelial component was composed of low-grade endometrioid glands that focally showed an unusual oxyphilic change of the cytoplasm. These cells contained only a small amount of mitochondria detected with antimitochondrial antibody. The stromal component contained small round cells of bland appearance and appeared to arise from epithelial cells through a metaplastic process, as a gradual transition between epithelial and stromal cells was often seen. An invasive marginal zone of the tumor showed endometrioid adenocarcinoma pattern without any stromal component. The proliferative activity generally was low. Interestingly, it was clearly accentuated in the epithelial component especially in the peripheral invasive areas, whereas it was very low in the stromal component. The course of disease was indolent. Low-grade müllerian carcinosarcoma is to be distinguished from other biphasic müllerian tumors.

We present an unusual case of cutaneous carcinosarcoma with the epithelial component closely resembling nodular basal cell carcinoma, and the mesenchymal component composed of cells constituting extended follicular papillae. A solitary tumor was excised in an 80-year-old man. Histologic sections revealed an ulcerated, asymmetric, poorly circumscribed neoplasm composed of epithelial cells arranged in lobules with peripheral palisading or in a cribriform pattern. The epithelial cells were darkly basophilic with scant cytoplasm and round or oval nuclei with an indistinct chromatin pattern and nucleoli. Nuclei crowding and mitotic figures were observed. Some lobules contained melanin. There were no shadow cells, sebaceous or apocrine glandular differentiation. Each epithelial nodule was surrounded by multiple rows of cells with pale vesicular nuclei and scant cytoplasm. Smaller epithelial aggregations were encircled by these cells concentrically; in larger ones these cells were aligned across a broad front resembling so-called "continuous papillae". Additionally, numerous small follicular germ-like structures associated with papillae were seen. The cells composing "continuous papillae" showed nuclear pleomorphism, numerous mitotic figures including atypical ones, and nuclear crowding. At foci, the transition from the multilayered arrangement of these cells into their diffuse proliferation in the stroma was seen. There were no transitions between the epithelial and stromal component; both were intermingled as though being mutually dependent, with no areas revealing a high-grade tumor or dedifferentiation. Immunohistochemically, the epithelial cell component stained with cytokeratins. The cells of the mesenchymal component tested positive for vimentin and negative for desmin and cytokeratins. The proliferation index (Ki-67) was high in both components. There were also a high number of p53-positive cells in both compartments. We propose the term "low-grade trichoblastic carcinosarcoma" for this neoplasm. We are not aware of a similar tumor published in the English literature.

We present the case of a 74-year-old Caucasian male with an expansive process of the left kidney. No clinical and laboratory signs of polycytemia or hypertension were present. Microscopically, the spherical main tumor mass was composed of small basophilic cells arranged in longitudinal branching tubules typical of metanephric adenoma (MA). Another component, different from MA, was formed by a tumor in a papillary and tubopapillary arrangement. This component was diagnostic of grade 3 papillary renal cell carcinoma. The third component, which was merging with the papillary one, was composed of sarcomatoid, spindle cell carcinoma with prominent nuclear polymorphism and a high number of mitotic figures, including atypical mitoses. The sarcomatoid component filled the entire cortico-medullary space and infiltrated the surrounding non-neoplastic renal tissue, including the renal pelvis. Areas of necroses, hemorrhages, and mitotic figures were frequent. No structures of Wilm's tumor were seen in our case. One year after the excision, the patient is without recurrence and metastasis. The existence of the above mentioned tumor supports the hypothesis that metanephric adenomas and papillary renal cell carcinomas are interrelated lesions.
