BACKGROUND: Tinea unguium is a common problem seen in clinical practice. Considering the many differential diagnoses of dystrophic nails, it is important to make a definitive diagnosis of dermatophyte infection before the initiation of antifungal therapy. Potassium hydroxide (KOH) preparation and fungal culture, which are commonly used in the diagnosis of these infections, often yield false-negative results. Recent reports have suggested that nail plate biopsy (Bx) using periodic acid-Schiff (PAS) (Bx/PAS) stain may be a very sensitive technique for the diagnosis of tinea unguium. OBJECTIVE: The purpose of this study was to evaluate the usefulness of PAS and Grocott's methenamine silver (GMS) staining of nail specimen in the diagnosis of tinea unguium as a standard method. METHODS: We evaluated 75 nail specimens from suspected tinea unguium using KOH preparation, biopsy using periodic acid-Schiff stain, and Grocott's methenamine silver stain. RESULTS: Of the 75 nails which were negative on potassium hydroxide mounting, 43 and 39 cases were tested positive respectively on periodic acid-Schiff stain and Grocott's methenamine silver stain. CONCLUSION: Bx/PAS and Bx/GMS are the sensitive methods for the diagnosis of tinea unguium. They are indicated if clinical suspicion of onychomycosis is high and KOH preparation shows no fungal elements.

Basal cell carcinoma (BCC) is the most common malignant skin cancer, consisting of 70-75% of all malignant tumors of the skin. Nevertheless, BCC located on the scrotum is exceedingly rare. Exposure to ultraviolet light (UV) is the most frequent factor predisposing to the development of BCC. However, with BCC of the scrotum, the etiology remains unclear. We report a case of basal cell carcinoma of the scrotum in a 68-year-old male patient, a review of the literature.

Angiofibroma and shagreen patches are common cutaneous manifestations of tuberous sclerosis complex (TSC) and have significant physical and psychological repercussions for patients. Several treatments have been proposed to improve lesions; however, clear treatment guidelines have not yet been presented. Thus, we introduce a case of angiofibroma and shagreen patch improved by application of pulsed dye laser, ablative fractional CO2 laser, and topical rapamycin, and present clinical implications for the treatment of angiofibroma and shagreen patch in TSC.

Plexiform neurofibromas are benign proliferations arising from the peripheral nerves and represent one of the diagnostic features of neurofibromatosis type 1. We present a case of a 14-year-old boy, who had large vascular neurofibromatous elephantiasis associated with a giant cafe-au-lait patch on his lateral aspect of the left hemithorax. Although he had no perceptible symptoms, radiologic examination revealed mild thoracic scoliosis with left side convexity. Our treatment of the skin lesion was one-stage palliative tumor debulking.
