Solitary Renal Metastasis Arising from a Pulmonary Adenoid Cystic Carcinoma: A Case Report and Review of the Literature.

Adenoid cystic carcinoma (ACC) is a malignancy affecting the salivary glands and rarely involving the lung. Due to its rarity, primary lung ACC remains incompletely understood. We herein report the case of a 57-year-old female patient who was initially diagnosed with primary lung ACC and was treated by lobectomy.

Retroperitoneal ganglioneuroma causing chronic lower back and leg pain in an 80-year-old man: A case report.

Introduction: and importance: Retroperitoneal ganglioneuromas that cause lower back and leg pain are extremely rare and are often misdiagnosed. Surgical resection has excellent prognosis in long-term survival.

Pemphigus vulgaris possibly associated with application of a tissue expander in a patient with Crohn's disease and primary sclerosing cholangitis.

Pemphigus vulgaris (PV) is an autoimmune disease of the skin and mucous membranes characterized by suprabasal acantholysis and formation of blisters and erosions due to generation of IgG autoantibodies directed against desmosomal proteins. Tissue expanders are devices that, through controlled mechanical overstretch, are capable of generating new skin that is used to cover wounds or extended surgical defects. We report the case of a 13-year-old girl suffering from Crohn's disease (CD) and primary sclerosing cholangitis (PSC) who developed PV after application of a tissue expander for surgical removal of a giant congenital melanocytic nevus (GCMN).
