TL;DR: It is demonstrated that primary cutaneous mucinous carcinomas span a morphologic spectrum compatible to their mammary counterparts, and most lesions seem to originate from in situ lesions that may represent, using mammary pathology terminology, ductal hyperplasia, atypical ductal Hyperplasia or ductal carcinoma in situ or a combination of the three.

TL;DR: A series of 24 malignant neoplasms arising in preexisting benign spiradenoma, cylindroma, and spiradenocylindroma is presented, proposing using a more specific terminology with the precise description of the neoplasm components, rather than generic and less informative terms such as “spiradenocarcinoma” or “carcinomyosarcomatous.”

TL;DR: A review of institutional and consultation files is reported in order to select cases of hitherto unrecognized type of adenocarcinoma occurring in the tongue.

TL;DR: A series of 23 cases of a distinctive, hitherto poorly recognized low-grade adenocarcinoma, with several histologic features reminiscent of papillary carcinoma of the thyroid, which mostly but not exclusively occurs in the tongue, is presented, with the name “cribriform adenOCarcinomas of minor salivary gland origin (CAMSG).

TL;DR: Three cases of subcutaneous tumors with hybrid features of schwannoma-perineurioma and neurofibroma-perneurioma, which occurred in two women aged 50 and 52 years and one man aged 52, are presented.
