(38-42) These HPV-related squamous intraepithelial lesions may be subclassified into warty, basaloid
, and warty-basaloid types by histopathologic features.
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.
squamous cell carcinoma of the oesophagus: assessment for high-risk human papillomavirus and related molecular markers.
Histopathology revealed a polypoid lesion consisting of aggregations of neoplastic basaloid
cells, which were confined to the polypoid region [Figure 2]a.
There were also abrupt and gradual transitions of the basaloid
cells to squamous and ghost cells.
Histologically, BSCC shows basaloid
and squamous differentiation and presents clinical characteristics such as local recurrence and metastasis comparable to SCC.
Pilomatrixoma was diagnosed with the appearance of basaloid
hair matrix cells and eosinophilic anucleated shadow cells under histologic examination.
The patient, an immunocompetent woman, aged in her 90s, with multiple inoperable cutaneous basaloid
SCCs, was treated with a combination of systemic and intratumoral delivery of 9-valent HPV vaccine, authors of the case report wrote in JAMA Dermatology.
Rare cutaneous metastasis from a probable basaloid
carcinoma of the colon mimicking pyogenic granuloma.
The most important key feature of basal cell carcinoma at low power magnification are that the basaloid
epithelial cells of the tumour arising from the epidermis.
Histology of the sinonasal tumor retrieved after endoscopic debulking surgery revealed infiltration of solid sheets of basaloid
cells with vesicular nuclei, nucleoli, and mitoses separated by fibrous bands of collagenized stroma.
Histologically, nests of basaloid
tumor cells were seen with peripheral palisading and focal architectural clefting between the tumor cells and adjacent fibromyxoid stroma.
