Villonodular synovitis are a group of idiopathic lesions that affect the synovial surfaces of joints, tendon sheaths, and bursae, causing tumor-like lesions. Pigmented villonodular synovitis rarely affects the tendon sheaths; its occurrence in extra-articular sites is uncommon. This case is presented for the rarity of occurrence. The literature is also reviewed.
Oncocytic tumours of adrenal gland are rare lesions with approximately twenty-five cases being documented in literature. A majority of them are nonfunctional and benign. We report a case of adrenal oncocytoma in a 44-year-old male, who underwent a laparotomy for a large mass in the abdomen, which was located above the left kidney. Routine histopathological examination was suggestive of a benign tumour with cells resembling oncocytes. However, immunohistochemistry and electron microscopy helped to confirm the diagnosis of an adrenocortical oncocytoma.
Lupus vulgaris (LV)is a progressive form of cutaneous tuberculosis (TB)that may occur in a patient with a moderate or high degree of immunity. The incidence of LV has declined with that in TB; it is relatively uncommon even in developing countries. LV commonly presents in the head and neck regions as flat plaques. Variants of LV form huge, soft, tumor-like forms with deep tissue and cartilage destruction resulting in deformities. The authors report a case of LV in a patient who presented with an ulcero-proliferative growth in the lower extremity, mimicking a malignancy.
