Hansen Disease (leprosy) is an infectious disease that targets macrophages and Schwann cells, caused by the acid fast intracellular organism, Mycobacterium leprae. Clinically, it presents with a spectrum of findings that may include hypopigmented macules, erythematous plaques and nodules, and thickened or tender peripheral nerves. The most feared complication is mutilating damage to facial structures or digits resulting from loss of sensation in affected skin. In non-endemic areas, the diagnosis of leprosy is frequently delayed because it may mimic other more common skin conditions. We present a case of borderline/lepromatous leprosy in an otherwise healthy young Brazilian man that was initially diagnosed as tinea versicolor, but did not respond to appropriate treatment. This case highlights the importance of having a high index of suspicion for leprosy in patients from endemic areas who present with lesions that could be consistent with this disease.

Lepromatous leprosy (LL) represents the highest infective and multibacillary form of leprosy. Clinical manifestations are consequent to the haematogenous spread of bacilli and include macules, plaques and nodules in a symmetric distribution or a diffuse infiltration of the skin. LL may mimic many different inflammatory and neoplastic skin diseases and in a small percentage of patients, skin manifestation may be atypical. This article reports the case of a South American child with LL presenting with symmetrically distributed hypopigmented macules previously misdiagnosed as pytiriasis alba, atopic dermatitis and pityriasis versicolor. Atopy and pityriasis versicolor are common skin conditions that can be also observed in leprosy patients and that can masquerade the diagnosis of LL, especially if occurring in dark skin. Dermatologists in Europe should be aware of this unusual form of presentation of leprosy and must take in mind Hansen disease in the differential diagnosis in patients coming from endemic areas.

BACKGROUND: In the last 10 years, different studies have shown interesting geographical variations in the prevalence of different Malassezia species in pityriasis versicolor. AIM: Identification of Malassezia species isolated from patients with pityriasis versicolor. METHODS: In 100 patients with pityriasis versicolor, Malassezia species were identified by culture in Sabouraud's dextrose agar containing cycloheximide with olive oil overlay and modified Dixon agar and by doing biochemical tests (catalase reaction, assimilation of glycine, and Tween utilisation tests). RESULTS: In 10 patients, 10% KOH smear was negative, while in 90 patients the smear showed characteristic "spaghetti and meatball" appearance. Of these 90 cases, growth was obtained on modified Dixon's agar in 87 cases. Fifty of the isolates (57.5%) were M. globosa, 15 (17.2%) were M. sympodialis, seven (8.0%) were suspected M. sympodialis, 6 (6.9%) each of the isolates were M. furfur and M. obtusa, and three (3.4%) isolates were M. restricta. CONCLUSION: M. globosa was the most common species, followed by M. sympodialis, M. furfur, M. obtusa, and M. restricta.

OBJECTIVES: To determine the pattern of psychiatric morbidity prevalent among leprosy patients and to compare it with two control groups; those suffering from Tinea vesicolor and Normal subjects. DESIGN: Eighty-eight leprosy patients were matched for age and sex with those suffering from Tinea vesicolor as well as normal subjects. The subjects were assessed for psychiatric morbidity through a clinical interview with PSE-9. RESULTS: The prevalence of psychiatric morbidity among leprosy patients (580/1000) was significantly more than those with tinea vesicolor patients (182/1000) and normal subjects (148/1000) (p < 0.05). Depressive illness was the most common diagnosis in the three groups. CONCLUSIONS: Leprosy patients are more likely to manifest with psychiatric illness than those suffering from Tinea vesicolor and normal subjects.

BACKGROUND: Pityriasis versicolor (PV) is a mild but recurrent superficial fungal infection of stratum corneum. Many predisposing factors such as late teen and young adulthood age, tropical and subtropical climate (and to a lesser extent temperate climate), immunosuppression, malnutrition, use of oral contraceptives, hyperhidrosis, poor hygiene and a few other factors have been proposed for this condition. AIM: Regarding these probable and possible risk factors, we felt that jail is a unique population which can be affected by this infection and therefore we decided to evaluate some aspects of this infection in this population. METHODS: In this cross-sectional study in male prisoners of Bandarabbas city, 230 prisoners were randomly selected. One hundred and five (45.67%) of them were diagnosed to be infected. They were also evaluated regarding age, duration of being imprisoned, skin color, site of lesion and its pigmentation change and any concomitant clinical manifestation such as pruritus, burning or cebure. Chi-square test or Fisher's exact test was used for data analysis. RESULTS: Mean age of infected population was 31.62 +/- 8.67 years while peak incidence of PV was in 28-32 years age group. The most common color change was hypopigmentation. No case of PV hyperpigmentation was seen. We could not also observe any association between skin color and duration of being imprisoned with the frequency of infection. CONCLUSION: There seems to be no difference between pattern of infection in the general population and prisoners' population in the aspects evaluated.

This report describes the case of a young woman from Mayotte (Comoros Islands) who presented a combination of three cutaneous diseases, i.e. pityriasis versicolor, scabies, and multibacillary leprosy. Symptoms of leprosy were concealed by those of the other two diseases. After multidrug therapy for leprosy, the patient developed erythema nodosum leprosum that was successfully treated using pentoxifylline. Combination of cutaneous diseases can alter usual presentations and lead to misdiagnosis. It is important to take into account possible disease combination to establish proper diagnosis and prescribe effective treatment.

BACKGROUND: Pityriasis versicolor (PV) is a mild chronic infection of the skin caused by Malassezia yeasts. Although it is primarily seen in adults, children are often affected in the tropics . METHODS: Over a period of 2 years, children (up to the age of 14 years) who were clinically and mycologically diagnosed as PV were included in the study. The clinical and epidemiological pattern in different age groups was noted. RESULTS: PV in this age group formed about 31% of the total cases of PV; 4.8% cases presented in infancy. The commonest site of involvement was the face in 39.9% of the cases. Most of the cases presented in summer months. CONCLUSIONS: PV is not an uncommon disease among children in the tropics. There is a sudden resurgence of cases in the hot monsoons and even infants are not spared.

Cysticercosis, an infection with the larva of Taenia solium, is caused by the accidental ingestion of the parasite's eggs. In many countries of the Third World, cysticercosis, and especially neurocysticercosis, is a widespread problem. A patient from Northern Malawi presented not only with cysticercosis but also with BT leprosy and pityriasis versicolor. Dermatologists should be familiar with the clinical picture of cysticercosis in order to make an early diagnosis in patients from at-risk areas.
