RESUMEN
Proliferating trichilemmal (pilar) cysts, also known as pilar tumors, are most commonly found on the scalp of elderly women. Proliferating trichilemmal cysts are rare, slowly growing, lobular masses inherited autosomal dominantly and localized on scalps, and believed to arise due to a complication of a trauma and inflammation, and 5-10% of people are reported to be effected. Herein, we present the case of a 70-year-old woman with a 23-year history of multiple enlarging scalp masses. Clinically, squamous cell carcinoma was considered in the differential diagnosis, and the lesion was totally excised. Our case emphasizes the necessity for detailed clinical and pathological correlation for differential diagnosis.
RESUMEN
A 35-year-old woman presented with a thyroid mass, weakness and shortness of breath of 3 years duration. On physical examination, she had a diffusely enlarged thyroid gland with multiple nodules. There were no signs to suggest immune suppression. The patient farmed and raised livestock. Biochemical tests and hemogram were normal. She underwent surgery, and a histological examination of the surgical specimen revealed nodular hyperplasia. Microscopically, silver methenamine (PASM) stain-positive hyphae that divided into branches at 45° and conidia were detected beside the thyroid capsule, with conidia in the cystic nodule. Moreover, ischemic changes of the thyroid tissue were observed closer to the capsule. We report a case of Aspergillosis of the thyroid of a patient who underwent surgery for a multinodular goiter.
