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.

Nodular fasciitis is a benign, reactive, myofibroblastic, proliferative process of unknown etiology. It presents as a solitary, painless, rapidly-growing nodule over several weeks' duration. The condition is self-limiting, and proper diagnosis is essential to avoid unnecessary aggressive treatment. Diagnosis is often a challenge because nodular fasciitis may be confused with a malignant tumor due to its aggressive clinical behavior and histological features. It is most commonly located on the extremities and then the trunk. Such lesions also usually occur in middle age and are rarely diagnosed in childhood. We report a case of recurrent nodular fasciitis that arose from subcutaneous tissue on the back of a pediatric patient.
