Giant basal cell carcinoma: a clinical red flag

Giant basal cell carcinoma (GBCC) is a rare and more aggressive variant of basal cell carcinoma. We present a case of GBCC with an overview of the challenges it presents.A man in his 60s presented to the tertiary care unit with a history of an ulcer over the posterior aspect of his left heel for the past 1 year. Examination revealed an ulceroproliferative lesion of 10×8 cm on the posterior aspect of the left heel and lower Tendo-Achilles region. A wedge biopsy of the lesion was performed twice, which demonstrated basal cell carcinoma. The patient underwent excision of the lesion with 10 mm margins. A split-thickness skin graft was placed and secured over the resultant wound with the application of a negative pressure wound dressing.The correlation between tumour size and tumour behaviour is examined. Additionally, the significance of tumour location, width of margins, incidence recurrence or metastasis is also studied.
