“…A cornoid lamella of porokeratosis and adjacent BCC or melanoma were identified in the same specimen, an observation which has never been reported to date. Mucosal porokeratosis lesions are infrequent 7,8 . We are not aware of any other case of EC arising in porokeratosis with mucosal involvement.…”

“…The lesions are characterized by seed‐like punctuate keratoses with thin, raised margins and/or pits, which may be tender to pressure. PPPD is an uncommon variant of PP with lesions appearing on all areas of the body 19–22 . Lesions of PPPD are relatively uniform and thick.…”

Porokeratosis represents a group of disorders of epidermal keratinization which are characterized by the histopathological feature of the cornoid lamella, a column of tightly fitted parakeratotic cells. The aetiology of porokeratosis is still unclear. This review summarizes the currently available data on the pathophysiology of this condition and discusses the clinical variants and the currently available therapies.

A 74-year-old woman presented with skin squamous cell carcinomas on both palms, ankles and soles. The patient also had biopsy-proven porokeratosis. There was hyperkeratosis of the palms and soles. The left palm cancer was excised and skin grafted, but recurred. A nodule in the scar of the donor site of the skin graft in the left upper arm was biopsy-proven squamous cell carcinoma. A metastatic left axillary lymph node was excised. There were no palpable metastatic lymph nodes in either the groin or right axilla. All cancers were irradiated and disappeared, as did the incidentally irradiated hyperkeratosis. Porokeratosis may be associated with skin squamous cell carcinoma, yet in this case porokeratosis could not be identified in the heavily hyperkeratotic palms and soles. Despite poor prognostic signs, i.e. the location in the palm, and metastasis, the patient has done well so far.
