Case from Dr Shahbaz Janjua
Tinea nigra is an uncommon superficial dermatomycosis usually caused by Hortaea werneckii. The infection appears as a hyperpigmented macule, which most commonly occurs on the palms but soles may also get involved. The pigmentary change in the skin results in a dark-colored macule due to the accumulation of a melaninlike substance in the fungus. Tinea nigra is believed to occur as a result of inoculation from a contamination source such as soil, sewage, wood, or compost subsequent to trauma in the affected area.

Case from Dr Ian McColl
The case of seborrhoeic dermatitis illustrated here shows large patch areas on the cheeks, sometimes called a petaloid pattern, although the latter is more commonly seen on the anterior chest wall. The condition on the face is best treated with some Nizoral (Ketoconazole) cream with a weak topical corticosteroid such as 1% hydrocortisone cream applied at night for persisting inflammation.
