Dental Sinus

Case from Dr Kiran Nabar
This patient had history of recurrent painful tender swelling occurring on left side of jaw since last 1 year. It used to burst open to discharge pus. It used to heal with antibiotic just to recur again within 1 to 2 months. The skin was adherent to the underlying mandible. Extraction of the corresponding infected molar cured the problem for ever.

Case from Dr Ian McColl
Flexural pityriasis rosea is a less common presentation of this condition and in my experience takes longer to settle than the typical variant on the trunk.

Molluscum contagiosum is a benign viral disease of the skin caused by a DNA virus of the poxvirus group. The virus is spread by physical contact with an infected individual or fomites.
How would you treat these lesions?

Case from Dr Ian McColl
This lady has previously had psoriasis elsewhere but recently developed these lesions acrally involving the fingers and toes. There were some preceding pustules but they are not evident today. There is marked nail dystrophy. The issue is whether this is simply acral psoriasis or the more unusual variant of acrodermatitis continua of Hallopeau?

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.
