Penile tuberculoid leprosy in a five year old boy.

A 5-year-old contact of a lepromatous leprosy patient with a tuberculoid lesion on the anterior aspect of the shaft of the penis is reported. The child was clinically suspected to have borderline tuberculoid leprosy during a survey of contacts of leprosy patients, which on histopathology revealed features of subpolar tuberculoid leprosy. The father of the child was recently detected as a case of lepromatous leprosy and was started on multibacillary regime of WHO multidrug therapy. The reason for the localization of the lesion to the shaft of the penis is also suggested. Skin as a route of transmission of tuberculoid leprosy is also emphasized.

Squamous cell carcinoma of the scalp arising from chronic cutaneous lupus erythematosus: report of two Indian patients.

Squamous cell carcinoma (SCC) usually arises in skin damaged by actinic rays. Exposure to chemicals like coal tar, soot, arsenic and a variety of oils and distillation products is also implicated in its pathogenesis. It occasionally occurs in scars following inflammatory or degenerative processes. It is an end stage complication of a wide array of inflammatory skin conditions. SCC complicating chronic cutaneous lupus erythematosus (CCLE) in Indian patients is rarely reported. Here we report two such Indian patients with long standing CCLE in whom the diagnosis of CCLE and SCC was confirmed by histopathology.

Elevated free tear lactoferrin levels in leprosy are associated with Type 2 reactions.

PURPOSE: To determine the association of demographics, leprosy and ocular characteristics with altered levels of lactoferrin in the tears of normal subjects and leprosy patients, and to detect the presence of antibodies to lactoferrin in these tear samples. METHOD: We collected light-stimulated tears from 298 leprosy patients and an equal number of normal subjects using the glass capillary method. Free lactoferrin levels were estimated using ELISA and the presence of antibodies to lactoferrin was detected using the immuno-blotting method. Significant associations were looked for between tear lactoferrin levels and demographic characteristics, leprosy characteristics such as type of disease, duration of disease, reactions, deformity and bacterial load, and ocular complications, using chi-square and regression analysis. RESULTS: Tear lactoferrin levels with a mean (SD) of 2.55 (2.83)mg/ml in the control group were significantly different (P<0.000) from leprosy patients with a smean (SD) of 5.66 (7.21)mg/ml. Age showed an inverse correlation with tear lactoferrin levels in controls. Increased bacterial load, grade 2 leg deformity and Type 2 reactions were significantly associated (P<0.05) with increased tear lactoferrin levels. Type 2 reactions remained significantly associated (P=0.01) on multiple regression analysis. Tear lactoferrin levels were not associated with gender, serum lactoferrin levels, Type 1 reactions, face patches, treatment status, orbicularis oculi weakness, lagophthalmos, ectropion, entropion, corneal opacity, cataract and iridocyclitis. CONCLUSION: Age is inversely related to tear lactoferrin levels in normal subjects. Free lactoferrin levels in tears are significantly higher in leprosy patients compared with normal controls. Type 2 reactions in leprosy are significantly associated with elevated tear lactoferrin levels.
