Background: Lymphangioma circumscriptum are benign hamartomatous lymphatic growths, diagnosed clinically by the morphology of groups of clear fluid filled to serosanguinous fluid vesicles. MRI is an essential investigation to assess the depth of the lesions. Aim: To report an interesting hitherto unreported observation of Reverse Koebner's phenomenon, which can be used as a new diagnostic technique in Lymphohemagioma. Method: Biopsy was taken for the confirmation of the lesion which is an inflicted iatrogenic trauma which showed Reverse koebner's phenomenon in the lesion. Results: Irregular shaped reddish blue painless plaque with rough lobulated surface with discrete firm reddish‐blue painless papules, of varying sizes were biopsied. Post biopsy, significant reduction in size and redness of the lesions noticed. Conclusion: Disappearance of the lesions on biopsy indicates reminiscensce of the reverse koebner's phenonmenon.

Abstract: Erythema nodosum migrans (subacute nodular migratory panniculitis) is an uncommon type of panniculitis characterized by migrating subcutaneous nodules or plaque on the lower extremity. There are a very few cases of Erythema nodosum migrans reported and thus its appropriate treatment modality is not defined. We describe a case of a 30‐year‐old male with idiopathic erythema nodosum migrans which was manifest centrifugally spreading, slightly morpheaform erythematous plaque on the lower left leg. The patient was diagnosed initially and treated as a case of furunculosis with poor clinical response. The skin biopsy showed features consistent with subacute nodular panniculitis. Saturated Solution of Potassium Iodide along with topical Heparin successfully treated the patient, when the conventional treatment modalities failed. In a morpheaform centrifugally expanded plaque, erythema nodosum migrans should be kept in mind in the differential diagnosis, especially in the lower extremities in cases of unknown etiology.

Cholecalciferol (vitamin D) might play a physiological role in photo-induced melanogenesis in human skin. We estimated the levels of 25-hydroxy vitamin D [25(OH)D] before, during, and after Narrow Band Ultraviolet B (NBUVB) radiation in patients of vitiligo and their correlation with NBUVB induced pigmentation. Thirty patients of vitiligo and equal number of age and sex matched controls were recruited for the study. Vitiligo patients were treated with NBUVB thrice weekly for 12 weeks. [25(OH)D] levels and Vitiligo Area and Severity Index (VASI) were calculated at 0 (baseline), 6, and 12 weeks. Baseline [25(OH)D] levels were measured in controls. Significant reduction in VASI score was observed after 12 weeks of therapy. Comparison and correlation between mean improvement inVASI and [25(OH)D] levels at 12 weeks showed moderate correlation, and the results were statistically insignificant. Mean reduction in VASI and increase in [25(OH)D] levels after 12 weeks of NBUVB showed moderate correlation. Thus, vitamin D might play a significant role in photo-induced melanogenesis. However, there might be additional effects of the phototherapy on melanogenesis. The complete mechanism of NBUVB induced pigmentation in vitiligo needs to be elucidated. [ABSTRACT FROM AUTHOR]
