Recent Advances on Immunohistochemistry and Molecular Biology for the Diagnosis of Adnexal Sweat Gland Tumors.

Cancers (Basel) 2022 Jan 18;14(3). Epub 2022 Jan 18.

French Network of Rare Skin Cancers, CARADERM, France.

Cutaneous sweat gland tumors are a subset of adnexal neoplasms that derive or differentiate into the sweat apparatus. Their great diversity, rarity, and complex terminology make their pathological diagnosis challenging. Recent findings have revealed a wide spectrum of oncogenic drivers, several of which are of diagnostic interest for pathologists. Read More

Acquired nasolacrimal duct obstruction: clinical and histological findings of 275 cases.

BMC Ophthalmol 2022 Jan 5;22(1):12. Epub 2022 Jan 5.

Centre of Eye Diseases, Vilnius University Hospital Santaros Klinikos, Santariskiu 2, LT-08661, Vilnius, Lithuania.

Background: Acquired nasolacrimal duct obstruction is a blockage of the lacrimal outflow system usually caused by local nonspecific inflammation of the lacrimal sac and the nasolacrimal duct. However, cases exist where the primary nasolacrimal system obstruction is caused by malignancies. Our aim was to investigate lacrimal sac pathologies in patients with acquired nasolacrimal duct obstruction and compare their clinical manifestations. Read More

Giant eccrine acrospiroma of the scalp.

J Cutan Aesthet Surg 2021 Apr-Jun;14(2):238-240

Department of General Surgery, Kasturba Medical College, Manipal Academy of Higher Education, Manipal, Karnataka, India.

Eccrine acrospiroma is a benign skin tumor that arises from the ducts of sweat glands, presents as small solid or cystic lesions that rarely can undergo malignant transformation, and leads to a diagnostic dilemma. We report a 32-year-old woman who presented with a large pedunculated tumor of the scalp that was excised and histopathologically proven to be a giant eccrine acrospiroma. This case is being presented because of its infrequent occurrence and the unusual large size of the lesion on the scalp that has been not reported in the literature so far. Read More

Three Cases of Clear Cell Hidradenoma With "Benign" Lymph Node Involvement.

Am J Dermatopathol 2021 Jun;43(6):e76-e79

Department of Pathology, Hospital Universitario Doce de Octubre, Universidad Complutense, Instituto de Investigación I+12, Madrid, Spain; and.

Abstract: The malignant counterpart of cutaneous clear cell hidradenoma (CCH), hidradenocarcinoma, is an aggressive neoplasm that may have a fatal outcome. However, some cases of benign looking CCH with isolated lymph node involvement and excellent prognosis have been described. "CCH-like neoplasm of uncertain malignant potential" or "atypical hidradenoma" have been proposed as designations for these lesions. Read More
