Co-Occurrence of Pityriasis Amiantacea and Cutis Verticis Gyrata Secondary to Leukaemia Cutis of the Scalp

A 32-year-old man with B-cell acute lymphoblastic leukaemia (B-ALL) presented with severe scalp scaling and hair loss, diagnosed as pityriasis amiantacea (PA) with secondary cutis verticis gyrata due to leukaemia cutis. This case is notable as it is the first reported instance of PA occurring as a consequence of leukaemia cutis, a rare condition where leukaemia cells infiltrate the skin. The co-occurrence of PA and cutis verticis gyrata is also rare and underscores the importance of clinician awareness for accurate diagnosis and management.
