Carcinosarcoma of the vulva: a rare case report

Carcinosarcomas are rare and clinically aggressive neoplasms with poor outcome. A very few cases has been reported in the literature. We present a case of a 54 yrs woman with bleeding per vagina for 1.5 months. On per vaginal examination, a lump of size 3×2 cm was found over the left anterior region of vulva. CECT abdomen revealed a well-defined heterogeneously enhancing lesion with calcific foci involving both labia minora. MRI pelvis reveals carcinoma left vulva with involvement of lower 3rd of vaginal wall. Histopathological examination showed features suggestive of carcinosarcoma of the vulva. This was further confirmed by immunohistochemistry which showed positivity for CK, SMA, caldesmon and negative for S100, CD34, desmin, CD31, ERG and MyoD1. Because it is a very rare tumor with severe prognosis, we presented this case as this case report can be a useful addition to the literature.

Oral squamous cell carcinoma with clear cell change: a rare case report

Clear-cell variant of oral squamous cell carcinoma is an extremely rare entity. Clear-cell change can be seen in any of the neoplasms, but as pure form variant, it is difficult to find in head-and-neck SCC. We hereby present a case report of 71-year-old male who presented with a growth with erythematous patches on the lateral pharyngeal wall for the past 3 months. Histopathologic examination showed nests, islands and sheets of malignant squamous cells with vesicular nuclei and abundant clear cytoplasm. Neoplastic cells constituting majority of nests exhibited clear cell changes. Special stain was performed to identify the nature of clear cells. periodic acid Schiff-diastase (PAS-D) showed positivity in the clear cells. Immunohistochemical study using antibody for pan-cytokeratin revealed diffuse positivity in the tumor cells
