Lupoid cutaneous leishmaniasis: A report of 16 cases.

Background: Lupoid cutaneous leishmaniasis (CL) is known as the chronic form of CL. However, keeping its clinical presentation in view, there is a need to revisit this form of disease. Aims: To redefine/describe lupoid CL in view of clinical features. Methods: It was a case series seen in Muzaffarabad (Pakistan) from Jan 2006 to May 2008. All patients clinically suggestive and consistent with laboratory diagnosis of CL were registered. Patients of all age groups and either sex having cutaneous lesions resembling lupus vulgaris or lupus erythematosus on the face or elsewhere were included in the study. Those having chronic fluctuating/relapsing course or scarring within the lesions were also included. Various demographic features of the patients and clinical patterns were recorded. Descriptive statistics were used for analysis. Results: Of 254 registered patients of CL, 16 (6.3%) were diagnosed as lupoid CL. None of the patients had scarred lesions. Age ranged from 38 to 75 (55 + 15.11) years and duration of lesions varied from 4 to 32 (14.25 + 07.59) weeks. All patients had lesions over the face. Thirteen (81.25%) had a large solitary plaque extending over the nose and a large part of the cheeks and three (18.75%) had multiple lesions. Lesions were central/nasal in two (12.5%), unilateral/asymmetrical in four (25%) and bilateral/symmetrical in 10 (62.5%). Morphological patterns included erythematous/infiltrated (7), psoriasiform (6), ulcerated/crusted (2) and Discoid lupus erythematosus (DLE)[G1] like (1). Conclusion: Lupoid CL is not strictly a chronic form of disease, which presents on the face from the very onset and shows no scarring or recurrence.

Many faces of cutaneous leishmaniasis.

BACKGROUND: Cutaneous leishmaniasis (CL) is known for its clinical diversity and increasing numbers of new and rare variants of the disease are being reported these days. AIM: The aim of this descriptive study was to look for and report the atypical presentations of this common disease occurring in Pakistan. METHODS: The study was carried out in three hospitals (MH, Rawalpindi; PAF Hospital, Sargodha; and CMH, Muzaffarabad) from 2002 to 2006. Military and civilian patients of all ages, both males and females, belonging to central and north Punjab province and Kashmir were included in the study. Clinical as well as parasitological features of cutaneous leishmaniasis were studied. The unusual lesions were photographed and categorized accordingly using simple descriptive statistics. RESULTS: Out of 718 patients of cutaneous leishmaniasis, 41 (5.7%) had unusual presentations. The commonest among unusual morphologies was lupoid leishmaniasis 14 (34.1%), followed by sporotrichoid 5 (12.1%), paronychial 3 (7.3%), lid leishmaniasis 2 (4.9%), psoriasiform 2 (4.9%), mycetoma-like 2 (4.9%), erysipeloid 2 (4.9%), chancriform 2 (4.9%), whitlow 1 (2.4%), scar leishmaniasis 1 (2.4%), DLE-like 1 (2.4%), 'squamous cell carcinoma'-like 1 (2.4%), zosteriform 1 (2.4%), eczematous 1 (2.4%), verrucous 1 (2.4%), palmar/plantar 1 (2.4%) and mucocutaneous 1 (2.4%). CONCLUSION: In Pakistan, an endemic country for CL, the possibility of CL should be kept in mind while diagnosing common dermatological diseases like erysipelas, chronic eczema, herpes zoster, paronychia; and uncommon disorders like lupus vulgaris, squamous cell carcinoma, sporotrichosis, mycetoma and other deep mycoses.

Congenital erythropoietic porphyria in three siblings.

Congenital erythropoietic porphyria is a rare autosomal recessive disorder that usually presents with marked skin photosensitivity, hypertrichosis, blistering, scarring, milia formation and dyspigmentation of the photo-exposed areas. Three adult siblings (two sisters and one brother) are presented here with variable degree of skin manifestations. During early childhood, all the siblings started showing signs of photosensitivity with darkening of urine color followed by skin blistering over the face and hands. The oldest showed severe sclerodermiform mutilation and the youngest exhibited an initial involvement with hypertrichosis. None of them had any history of convulsions, acute abdominal pain or joint pain. Woods lamp examination and laboratory investigations confirmed the diagnosis.

Tolerance and safety of superficial chemical peeling with salicylic acid in various facial dermatoses.

BACKGROUND: Chemical peeling is a skin-wounding procedure that may have some potentially undesirable side-effects. AIMS: The present study is directed towards safety concerns associated with superficial chemical peeling with salicylic acid in various facial dermatoses. METHODS: The study was a non-comparative and a prospective one. Two hundred and sixty-eight patients of either sex, aged between 10 to 60 years, undergoing superficial chemical peeling for various facial dermatoses (melasma, acne vulgaris, freckles, post-inflammatory scars/pigmentation, actinic keratoses, plane facial warts, etc.) were included in the study. Eight weekly peeling sessions were carried out in each patient. Tolerance to the procedure and any undesirable effects noted during these sessions were recorded. RESULTS: Almost all the patients tolerated the procedure well. Mild discomfort, burning, irritation and erythema were quite common but the incidence of major side-effects was very low and these too, were easily manageable. There was no significant difference in the incidence of side-effects between facial dermatoses (melasma, acne and other pigmentary disorders). CONCLUSION: Chemical peeling with salicylic acid is a well tolerated and safe treatment modality in many superficial facial dermatoses.
