Bowen’s disease (BD) is an in situ squamous cell carcinoma of
the skin. Pigmented Bowen’s disease (pBD) is a rare variant,
representing less than 2% of all BD cases. We report a case of
Giant pBD arising from seborrheic keratosis in a 65-year-old man.
The dermoscopy showed a scaly surface, structureless brown to
grey-black areas with dotted vessels, glomerular and reticulate
vessels, and a few brown globules. Histopathology was classical
with a “windblown appearance”; prominent melanophages were
seen in the dermis. Owing to the size and thickness of the plaque,
a wide excision with a split-skin graft was done. The graft uptake
was good, and the patient was followed up on days 4 and 26
post-surgery. We present our experience with the diagnosis and
management of this rare case of giant pBD. To the best of our
knowledge, such a case has not been previously reported.
