Recurrent bladder malakoplakia: A rare bladder lesion mimicking malignancy.

Background: Malakoplakia is a rare granulomatous disease that commonly involves the genitourinary tract with the urinary bladder being the most frequently affected site. It is characterized by histiocytes containing distinct basophilic calcified inclusions called Michaelis-Gutmann bodies. It is believed to result from abnormally functioning macrophages, with inclusions representing calcifications around incompletely digested bacteria.

Cutaneous Deciduosis: A Rare Cutaneous Lesion Mimicking Malignancy.

Cutaneous deciduosis is an extremely rare condition that clinically presents as a nodular lesion in the skin as a scar or neoplasm. Histologically, this may pose a diagnostic challenge simulating malignant epithelioid neoplasms including sarcoma. Histologically, a nodular growth pattern of large monomorphic epithelioid cells is observed.

Primary Mucinous Carcinoma of Skin: A Rare Cutaneous Neoplasm. Clinicopathologic Features, Differential Diagnoses, and Review of Literature.

Primary mucinous carcinoma of the skin (PMCS) is a rare malignant neoplasm of sweat gland origin, with an incidence of 0.07 per million. Histologically, it may be difficult to differentiate it from metastatic mucinous carcinomas of the skin.

Mixed Epithelial and Stromal Tumor: A Rare Renal Neoplasm-Case Report with Clinicopathologic Features and Review of the Literature.

Mixed epithelial and stromal tumor (MEST) is a rare benign renal neoplasm composed of epithelial and stromal components. Here, we report a 61-year-old woman presenting with a left complex cystic renal mass. The lesion was found incidentally on ultrasound for abdominal discomfort.
