Histopathology of telomerase reverse transcriptase promoter () mutated indeterminate thyroid nodules.

Objective: The objective of this study was to analyze the risk of malignancy and the histopathology of telomerase reverse transcriptase promoter mutated cytologically indeterminate thyroid nodules (ITN).

Methods: A PUBMED search of molecularly tested ITN was conducted and data on mutated ITN with histopathology correlation were extracted.

Results: Twenty-six manuscripts (published between 2014 and 2022) reported on 77 mutated ITN.

Microcystic adnexal carcinoma of the head and neck: Characteristics, treatment, and survival statistics.

Studies on microcystic adnexal carcinoma (MAC) survival rates have been limited. This effort examines the association of patient demographics, treatment modalities, and tumor stage with overall survival (OS) in patients with MAC of the head and neck. All cases of MAC with primary sites of the skin of the head and neck, confirmed histologically, and diagnosed from 2004 to 2016 in the National Cancer Database, were analyzed.

Analysis of Head and Neck Primary Cutaneous Mucinous Carcinoma: An Indolent Tumor of the Eccrine Sweat Glands.

Background/objectives: Primary cutaneous mucinous carcinoma (PCMC) of the head and neck is a rare pathologic entity that is an adenocarcinoma of the eccrine sweat glands. Though it has low metastatic potential, it does have a significant recurrence rate. Due to its rarity, its clinical features are not well-known.
