Multifocal epithelial hyperplasia (MEH), also known as Heck's disease, manifests as a papulonodular lesion in the oral mucosa and has been associated with the human papillomavirus, a virus related to various precancerous diseases in the oral cavity. It has a predisposition for the female gender and for children. Although the majority of reported cases have been among American Indians and Eskimos, it has been described in multiple ethnic groups in various geographical locations. The objective of this review was to report on the clinical characteristics and epidemiology of MEH and its possible correlation with oral cancer. It is based on a search of articles in international journals published prior to April 2011, using the PubMed database and selecting articles related to the epidemiology and clinical characteristics of MEH. The review revealed a higher number of cases in individuals of American Indian origin and a predilection of the disease for the female gender and for patients between the 1st and 2nd decades of life. The most frequent lesion site was the lower lip. The disease has been associated with socio-economic and genetic factors, among others. No cases of malignant transformation have been reported.

: Thyroglobulin (Tg) is the specific tumor marker for epithelial thyroid cancer. It holds significant value in the postoperative period, and somehow, the goal of surgery in papillary thyroid cancer (PTC) undergoing total thyroidectomy is to achieve undetectable levels of postoperative thyroglobulin (uTg). : This is a retrospective single-center study in which first basal Tg values were evaluated post-surgery in PTC patients undergoing total thyroidectomy.

Solitary fibrous tumors (SFTs) of the central nervous system (CNS) are rare mesenchymal tumors characterized by a fusion of the NGFI-A-binding protein 2 (NAB2) gene and the signal transducer and activator of transcription 6 (STAT6) gene, immunohistochemically resulting in nuclear expression of STAT6 - an immunohistochemical hallmark essential for diagnosis, as outlined in the fifth edition of the World Health Organization Classification of Tumors. Dedifferentiation, where low-grade tumors transform into high-grade forms, has been observed in SFTs, with documented cases involving sarcomatous or rarely epithelial transformations. We report the first case of a CNS SFT exhibiting "transdedifferentiation" into epithelioid neuroendocrine differentiation.
