Pigmented BCCs

Pigmented BCCs2

History

          A 65-year old man presented with two rounded red plaques with well-demarcated, thread-like pigmented borders about 2 cm diameter  involving the chest and back. Both lesions cured with twice daily applications of Efudix (5 FU) ointment for 8 weeks.
* The interesting and peculiar aspect in this case is the occurrence of two BCCs simultaneously and on covered part of the body (trunk) in a patient with no risk factor except his age.

Infantile psoriasis2

History

           A very interesting and strange case of red scaly oval plaques with central hypopigmentation involving the trunk specially the abdomen in a 2-month old infant of three weeks duration. Few other lesions were clasical psoriatic plaques on the forearms and thighs. On mometasone ointment once daily the rash has almost cleared within 2-3 weeks (see the second photo).

Acrodermatitis continua suppurativa

Acrodermatitis continua suppurativa2

History

          The relation of acrodermatitis continua suppurative (Hallopeau) to psoriasis is controversial. However, some consider it as a localized form of psoriasis characterized by pustules limited to one or a few fingertips including the nail bed. Nail loss is not uncommon. Herein we present a typical case of acrodermatitis continua of Hallopeau characterized by chronic inflammation and pustulation confined to one finger (thumb) with nail loss of more than three years duration.
