Ectopic thyroid in an adrenal mass: a case report

BACKGROUND: It is difficult to explain ectopic thyroid beneath the diaphragm because during the development the thyroid descends from the tongue to the anterior of the trachea. A few cases of ectopic lesions have been reported in the literature for abdominal organs including the adrenal glands, but the mechanism by which the thyroid components migrate into the abdomen has been poorly understood. CASE PRESENTATION: A 54-year-old woman was diagnosed as having an adrenal mass. Laparoscopic adrenalectomy was carried out. Microscopically, the mass was composed of normal adrenal and ectopic thyroid tissues. CONCLUSION: We herein describe the fourth case reported of ectopic thyroid in the adrenal gland

Langerhans cell histiocytosis on the penis: a case report

BACKGROUND: Langerhans cell histiocytosis affects mainly young children and features an accumulation of CD1a+ dendritic Langerhans cells in the bone, skin, and other organs. A few cases of Langerhans cell histiocytosis on the penis have been reported in the literature. We present a case of Langerhans cell histiocytosis on the penis and review the similar cases in the literature. CASE PRESENTATION: The patient was a 13-year-old boy who had a history of lymph node, femur bone, and pituitary-thalmic axis lesions from Langerhans cell histiocytosis who noticed a painful nodule on the prepuce of his penis. The histological and immunohistochemical examination fulfilled the criteria of Langerhans cell histiocytosis. CONCLUSION: We herein describe the case reported of Langerhans cell histiocytosis on the penis
