Squamous cell carcinoma (20 patients), metatypical carcinoma (6 patients), and malignant melanoma (2 patients) were the other histopathologic diagnoses among malignant tumors.
BerEP4 was positive within the basaloid tumor cells but negative in metatypical and intratumoral melanocytes [33, 48].
Aggressive-growth BCC variants, including micronodular, infiltrative, morpheaform, and metatypical, share features of increased cell necrosis, mitotic activity, and stromal proliferation, with a decreased demonstration of stromal retraction, deeper growth, and less circumscription.
Furthermore, GBCC is characterized by an aggressive histological subtype (morpheaform, micronodular, and metatypical) [2].
The latter included the infiltrative, morpheic, micronodular and metatypical (basosquamous) subtypes.
Features of biopsy in diagnosis of metatypical basal cell carcinoma (Basosquamous Carcinoma) of head and neck.
This carcinoma is also known as metatypical carcinoma, basaloid squamous cell-carcinoma, and basal squamous cell-epithelioma.4 While the rate of recurrence is low in BCC, BSCC tends to recur.
The histopathological subtypes of BCC in this study were classified into nine major patterns: Nodular, superficial, micronodular, infiltrative, keratotic, morpheaform, metatypical, adenoid, and infundibulocystic types.
Metatypical carcinomas with squamous differentiation in histological evaluations were excluded.
For example, keratotic BCC and metatypical BCC are very similar to basaloid SCC in H and E prepared microscopic
It is a common trend to call such tumors as metatypical or basosquamous carcinomas.
