Abstract

Carcinosarcomas of the lung are uncommon neoplasms and are presently categorized along with sarcomatoid carcinomas in the WHO 2004 classification. Morphological recognition of individual components in a surgical specimen is usually straightforward. The respiratory epithelium is also a rare site for salivary gland type tumors. A 72-year-old lady who was investigated for an episode of hemoptysis was found to have a well circumscribed intraluminal tumor. The histo-morphological features were unique and composed of mucoepidermoid carcinoma and undifferentiated sarcoma. To the best of our knowledge, this unusual morphological combination has never been reported in literature.

Abstract

Sclerosing angiomatoid nodular transformation of the splenic red pulp has been described quite recently; many of the lesions previously diagnosed as splenic exuberant granulation tissue, multinodular hemangioma, and inflammatory pseudotumor could actually belong to this category. The lesion has been well reported intermittently in the past, but new cases with still newer associations keep appearing from time to time. There are no known risk factors and no inciting triggers have been proven. We report two such cases- one of which has extensive extramedullary haematopoiesis; a feature that has never been reported earlier. Clinico-morphological and radiological features along with pathogenesis are discussed in detail.
