Describe the treatment of tinea infections.

Describe the pathophysiology, skin lesions produced, and the treatment of tinea infections.

Please read and consider the information in the following scenario.

A 75-year-old Caucasian woman was seen at a nearby community clinic for a raised lesion on her right thigh. She had noticed that the pale tan to light gray color of the lesion was changing. Examination by the referring experienced dermatologist showed a rough and coarsely granular, oval lesion with a slightly irregular border measuring 1.7 x 0.9 cm. Clinically, this lesion was thought to resemble an irritated seborrheic keratosis and was biopsied because of its size, a slight variability in color, and a clinical history of color change. The biopsy requisition diagnosis read “Irritated Seborrheic Keratosis.” Histopathologic examination of a deep-shave biopsy showed the low-power silhouette of a seborrheic keratosis, including squamous papilloma-like features and delicate, laminated pseudocysts of horn. The final diagnosis was malignant melanoma, superficial spreading type, Clark’s level III, Breslow 1.44 mm, probable vertical growth phase, and simulating a seborrheic keratosis.
