Cutaneous hidradenoma: a study of 21 neoplasms revealing neither correlation between the cellular composition and CRTC1-MAML2 fusions nor presence of CRTC3-MAML2 fusions


Kyrpychova, Liubov; Kacerovska, Denisa; Vanecek, Tomas; Grossmann, Petr; Michal, Michal; Kerl, Katrin; Kazakov, Dmitry V (2016). Cutaneous hidradenoma: a study of 21 neoplasms revealing neither correlation between the cellular composition and CRTC1-MAML2 fusions nor presence of CRTC3-MAML2 fusions. Annals of Diagnostic Pathology, 23:8-13.

Abstract

Twenty-one hidradenomas from 20 patients (13 female, 7 male) ranging in age from 18 to 87years (mean, 57.75years; median, 60years) were studied for CRTC1-MAML2 and CRTC3-MAML2 fusions to find out whether there is a correlation between the particular cell type (polyhedral eosinophilic, clear, mucinous, epidermoid, and oncocytic) and presence the above alterations. CRTC1-MAML2 fusions were detected in 10 of the 21 neoplasms (47.6%). Fluorescence in situ hybridization for MAML2 break apart was analyzable in 13 specimens and in all these specimens was positive, including 4 tumors with no demonstrable CRTC1-MAML2 fusion. In none of the cases was a CRTC3-MAML2 fusion detected. No obvious correlation between the cellular composition and presence of t(11,19) translocation was found.
