Thinking about the basaloid cell population in sebaceoma as homologous to the proliferative basal layer of a normal sebaceous gland should help observers accept and rationalize the presence of occasional mitoses in benign sebaceous lesions (Figure 3).
The basal cell carcinoma palisading arrangement of basaloid cell at periphery, squamous cell carcinoma (SCC) intercellular bridging or keratinization, malignant melanoma of large pleomorphic diffuse infiltration of large pleomorphic epithelioid tumor cell with melanin pigment and mucoepidermoid carcinoma sheets of mucous, squamous, and intermediate cells were found in Figure 1.
Basosquamous cell carcinoma (metatypic carcinoma, BSCC) of the dermis is a rare clinocopathologic entity which shows basaloid cell and squamous cell carcinoma properties.
They also exhibited a dermal lymphocytic infiltrate with abundant plasma cells, which was focally present around the basaloid cell aggregates.
Caption: FIGURE 3: Histological representation of metastasis in the left submandibular gland, showing basaloid cell strings (black arrows), with rounded and hyperchromatic nuclei, compatible with the cellular pattern of the primary site, from between the glandular stromata.
(23) These types of proliferation are referred to as follicular induction (FI) (also known as follicular basal cell hyperplasia, (24) epidermal basaloid cell hyperplasia (25) and basaloid epidermal proliferation).
Histology of excised tissue shows stratified squamous epithelium over fibrocollagenous stroma, cords and wide column of basaloid cell extending into the dermal stroma from overlying epithelium, rich vascularity within stroma in between these cords, confirming the diagnosis of periungual eccrine poroma.
In this study basaloid cell carcinoma of penis, esophagus and tonsil were found to be associated with alcohol and tobacco use.
Tubular and cribriform basal cell hyperplasia can be mistaken for adenocarcinoma, but again, the multilayered uniform basaloid cell population is the key finding that aids in diagnostic recognition.
Poorly differentiated tumors have irregular larger basaloid cell. On occasion they also demonstrate a microcystic pattern and contain isolated mucus--secreting cells.
A shave biopsy of one of the lesions was performed that showed a proliferation of nests of basaloid cells on the dermis with palisading and rare vacuolated clear cell change.
