75 yo woman with lesion of face

History: This 75 yo woman was first seen on 12 October 2004 with a lesion on cheek. It had a crust and some purulent material. The lesion was surrounded by large seborrheic keratoses and I thought it was an inflammatory seb ker. Ulcer care with cleaning and Bactroban cream was recommended. I gave her a follow-up appointment and saw her back yesterday.
Physical Exam: There is a 4 cm flesh-colored plaque on the left cheek. The borders are somewhat rolled. There is a crust centrally which when removed shows an ulcer and creamy pus. (see photos)
Lab: Culture obtained. Grew out normal skin organisms
Path: 3 mm punch biopsy obtained. Jan 5, 2005 - Report indicates well-differentiated squamous cell carcinoma
Diagnosis: I suspect SCC or KA. I think the purulent drainage may relate to the squamous cells - I saw a similar case years ago on the back that I thought was a ruptured epidermal inclusion cyst. This lesion has changed in the past two months. It looked quite benign at her last visit.
Jan 5, 2005. I discussed results with patient and she will be referred for micrographic surgery. Exam today reveals a possible submandibular lymph node. I wonder if this is related to chronic inflammation in the tumor rather than mets.

8 yo boy with lesion on wrist

History: The patient is an 8 yo boy with a one week history of an expanding lesion on the right wrist. He plays in a sandbox that is frequented by stray cats. He's been using clotrimazole cream for three days.
Physical Exam: There is a 2 cm diameter plaque on the right wrist. The periphery appears to be vesicular and possibly a bit scaly. No other lesions.
Lab: KOH equivocal - hard to interpret because of cream artifact.
Diagnosis: ? Kerion of glabrfous skin.
I plan to stop the cream, repeat KOH in a few days and have obtained a fungal culture. Will biopsy if still uncertain and process is progressing.

Follow-up of Jan 3, 2005. The patient was seen again and the KOH prep repeated. Today, this was markedly positive (no cream artifact) Dx: Kerion of Glabrous Skin. Usually caused by M. canis. See below for references.
