Agminated cellular neurothekeoma.

Cellular neurothekeoma represents a benign, slow-growing neoplasm that typically occurs as a solitary lesion on the face, neck or arm. Reports of multiple lesions are rare. To our knowledge, multiple lesions occurring as eruptive clusters localized to a single anatomical site has not been previously reported. This report details a case of an agminated cellular neurothekeoma occurring on the nose of a 28-year-old man. Recognition of multiple localized eruptive lesions of cellular neurothekeoma is important in order to facilitate correct diagnosis and avoid unnecessary treatment.

Parathyroid hyperplasia of auto-transplanted tissue in forearm skin.

Currently, the treatment of choice for refractory tertiary hyperparathyroidism is a total parathyroidectomy with autotransplantation of the parathyroid tissue into the forearm. Recurrent hyperparathyroidism after autotransplantation requiring surgical excision of the autograft is uncommon. We describe a female patient with recurrent hyperplasia who underwent an excision of her parathyroid autograft. The excisional specimen was submitted to pathology with the only provided history of a 'left arm mass'. The lack of clinical history led to a preliminary impression of an adnexal neoplasm by the primary pathologist.
