Sclerosing Polycystic Adenosis: A Rare Tumor of the Salivary Glands.

CASE PRESENTATION: A 74-year-old woman presented to the Head and Neck Surgery clinic with a 4-year history of a slowly growing, painful, left-sided neck mass in the tail of the parotid gland. Fine-needle aspiration suggested well-differentiated adenocarcinoma. DISCUSSION AND RESULTS: The patient underwent a superficial parotidectomy and super-selective neck dissection (level 2). Pathology revealed a tumor consistent with sclerosing polycystic adenosis. CONCLUSION: Sclerosing polycystic adenosis is a rare inflammatory process that causes fibrocystic changes in the salivary gland. Apocrine-like metaplasia and epithelial atypia are common pathologic features. To our knowledge, a total of 51 cases have been described in the English-language literature.

Myelolipoma in the spleen: a rare discovery of extra-adrenal hematopoietic tissue.

Myelolipomas are benign tumors usually found within the adrenal gland. Approximately 50 cases of extra-adrenal myelolipomas have been reported in the literature and all are associated with additional lesions. Myelolipomas contain hematopoetic cells and adipose tissue. Most commonly, they are asymptomatic and are found incidentally on radiologic imaging. Here we report a case of an isolated intrasplenic myelolipoma as an incidental finding during the work up for myasthenia gravis in an otherwise asymptomatic man. The spleen and associated mass were excised during laparotomy and the patient had an uneventful recovery.
