Recalcitrant ulcerative genital herpes in an immunocompetent individual treated successfully with imiquimod.

BACKGROUND: This case report describes the successful use of imiquimod to treat genital herpes in an immunocompetent individual with acyclovir-resistant HSV. CASE REPORT: A 32 year old male patient, presented with asymptomatic non-healing ulcers over the genital region for 2 years. The ulcers initially responded to acyclovir but became persistent after a few months. He also received multiple courses of antibiotics. On examination, the patient had bilateral inguinal lymphadenopathy and multiple painless ulcers over the coronal sulcus. Routine investigations were normal. The patient was treated with oral and intravenous acyclovir but showed no response. He was then started on topical imiquimod cream applied on alternate days. After one week, the patient presented with pain, redness, burning sensation, and fresh ulcer over the glans which were suspected to be imiquimod-induced irritant reaction or ulcer. Imiquimod was withheld for one week and then restarted at a twice-weekly schedule. After 1 month and 7 days of treatment with imiquimod at a twice-weekly schedule, there was healing of the ulcers. CONCLUSION: This case report illustrates the efficacy of imiquimod cream as a topical treatment for genital herpes simplex in an immunocompetent patient who had previously been unresponsive to treatment with acyclovir.

Mal De Meleda with Flexural Involvement.

Mal de Meleda is a rare variety of palmoplantar keratoderma with an autosomal recessive mode of inheritance and an estimated prevalence of 1 in 100,000 in general population. The disease is associated with consanguinity, starts in infancy, and characterized by progressive palmoplantar keratoderma spreading to dorsum of hands and feet. Involvement of extensors of knee and elbow were well described in literature. We report a rare case of Mal de Meleda with flexural involvement, which has not been reported in literature.

Clinico-Epidemiological Profile of Allergic Contact Dermatitis and Its Correlation With Patch Testing in a Tertiary Care Center in Eastern India.

BACKGROUND: Allergic contact dermatitis (ACD) is one of the most common skin disorders seen among patients attending dermatology clinics in India. Patch testing is the gold standard for diagnosing ACD. The clinical-epidemiological pattern of ACD and the allergen-causing it may be different in different geographic locations. Finding the profile of allergens commonly causing ACD in a particular region will help to formulate prevention strategies for the development of ACD. AIM AND OBJECTIVE: The primary aim of the study was to find out the clinical-epidemiological distribution of allergic contact dermatitis and to identify the common allergens causing it by patch testing in this region of India. MATERIALS AND METHODS: A total of 111 cases of ACD were included in the study. Clinico epidemiological profiles of all patients were documented. The patch testing was performed in the outpatient department using the antigens of the Indian Standard Series kit (Systopic Laboratories Pvt. Ltd., New Delhi, India). Patches were removed after 48 hours (two days) of application. The first reading was taken 15 to 20 minutes after the removal of patches on day two. A second reading was taken on day four (96 hours of application) to confirm the presence of an allergic reaction.  Results: The patch test was found to be positive in 69% of cases. It was observed that male persons from lower socioeconomic status were getting ACD on most accounts. Potassium dichromate (PDC) was found to be the most common allergen (30.43%) followed by parthenium (26.08%), para-phenylenediamine (PPD) (21.73%), nickel sulfate (18.84%), chlorocresol (15.94%), black rubber (14.49%), cobalt sulfate (13.04%), and wool alcohols (7.24%) respectively. CONCLUSION: Our study showed potassium dichromate is the commonest allergen causing ACD in this part of the country. The importance of patch testing lies mainly in educating the patient regarding the avoidance of exposure to particular allergens to avoid the development of new ACD as well as an exaggeration of pre-existing ACD.

Basidiobolomycosis: Case Report and Literature Overview.

Basidiobolomycosis or subcutaneous zygomycosis or subcutaneous phycomycosis is a chronic granulomatous infection of skin and subcutaneous tissue, caused by a saprophytic filamentous fungus, Basidiobolus ranarum, clinically characterized by firm, painless subcutaneous swelling with smooth and rounded edges. Histopathological features include the peculiar Splendore-Hoeppli phenomenon. Culture on Sabouraud dextrose agar shows creamy white, heaped up, and furrowed colonies. This entity has been reported from tropical and subtropical regions of the world and the southern part of India. We report a case of Basidiobolomycosis in a seven-year-old girl from Eastern India, which was excised twice before presenting to us. We diagnosed the case as Basidiobolomycosis based on clinical features, histopathology, and culture findings, and treated it with itraconazole.
