BACKGROUND: Permethrin shampoo is currently the first-line treatment for pediculosis capitis. However, its widespread use has resulted in the development of resistance.
OBJECTIVE: To compare aromatic oil shampoo and 1% permethrin shampoo in terms of efficacy and safety
METHOD: One hundred fifty-hour patients with active infestation were treated in this randomized, assessor-blind, controlled trial using aromatic oil or permethrin shampoo, applied once weekly for three weeks. Evaluations were conducted at baseline and a week after shampoo application. Complete cure was defined as the absence of live louse on day 21.
RESULTS: There were no significant differences between the two groups in terms of complete cure, changes in patient's quality of life and pruritus at day 21. Neither group reported any diverse effects.
CONCLUSION: The efficacy and safety of the aromatic oil shampoo was comparable to that of 1%permethrin shampoo in treating pediculosis capitis.

INTRODUCTION: Subungual squamous cell carcinoma is rare, though it is the most common primary malignant neoplasm in the nail unit. Fingernails are more commonly involved than toenails with nonspecific and mild features. Histopathologic presentation may be difficult to distinguish from other tumors. With this, there is often a delay in diagnosis.

CASE REPORT: A 64-year-old male presented with a subungual yellowish granulomatous plaque, eventual dystrophy, and persistent bleeding on the fi rst digit of the right foot of two years' duration. Initially diagnosed as pyogenic granuloma through skin punch biopsy, debridement with ungiectomy was done. Upon recurrence, he underwent wide excision with matricectomy, wherein deeper sections revealed features of basosquamous carcinoma. A positive Epithelial Membrane Antigen and negative BerEP4 staining later confirmed a diagnosis of SCC. Since bone involvement was repeatedly suspected in magnetic resonance imaging after postoperative radiotherapy, amputation was eventually done.

CONCLUSION: We report a case of subungual SCC initially diagnosed as a pyogenic granuloma. Full-thickness biopsy should be done in persistent nail conditions using special stains to confirm the diagnosis. Surgical treatment or radiotherapy with or without systemic therapy is the first line of treatment for subungual SCC. In cases of bone involvement, amputation may be warranted.
