Phyllodes tumor is a paradigm of fibroepithelial neoplasm that accounts for <1% of the breast neoplastic lesions usually detected in females and uncommonly in the male breast. The World Health Organization classifies the tumor into benign, borderline, and malignant based on the predefined morphological criteria. Squamous differentiation in phyllodes tumor is epithelial metaplasia, which has been occasionally documented in English literature. We report the first undocumented case of a recurrent borderline phyllodes tumor with cystic squamous metaplastic change in a 32-year-old male patient. The histology was that of a fibroepithelial neoplasm with the typical leaf-like projections and cystic spaces lined by squamous epithelium containing keratin debris. The purpose of presenting this case is to elucidate the pathogenesis and discuss other malignant and benign breast lesions that may be included in the differential diagnosis when evaluating a breast lesion with squamous metaplasia, particularly in the context of fine-needle aspirates.

Ovarian Sertoli Leydig cell tumors (SLCT) accounts for less than 0.5% of all ovarian malignancies. The incidence of primary extra-ovarian SLCT is extremely rare with reported cases occurring in young adult women till now. We report case of primary retroperitoneal extra-ovarian SLCT in a seven-year girl child without any hormonal manifestation. She presented with complaint of left side abdominal swelling associated with intermittent pain for a duration of six months. CT scan revealed a huge retroperitoneal space-occupying lesion abutting the dorsal vertebrae and present posterior to pancreas, spleen and left kidney. The tumor was diagnosed as extraovarian Sertoli Leydig cell tumor with intermediate differentiation on histopathology and immunohistochemistry.
