INTRODUCTION: Squamous Cell Carcinoma (SCC) includes several subtypes and these can be classified according to their clinical behaviours from the least invasive to the most aggressive. Moreover, it is appropriate to analyse their clinical pathological patterns I. In light of its wide histopathological variability, we encountered a rare malignant cutaneous lesion: a SCC of a proliferating trichilemmal tumour (PTT) nature.
CASE REPORT: We describe the clinical and pathologic findings of an 82-year-old woman, who developed a SCC with areas of trichilemmal differentiation. It has a surprising thickness of 25 mm, which passes through the dermis, infiltrates the hypodermic and evolves quickly.
CONCLUSION: Considering its exophytic growth and the negative results of the post operative tests (ultrasounds confirmed absence of metastasis), the tumour was eradicated thanks to the surgical approach (a 1 cm border wide excision, including the periosteum in the central part of the lesion, followed by its reconstruction using a full-thickness skin graft) and the prompt intervention, without need for further complimentary treatments. The overall aesthetic results were pleasing.
