Reverse Koebner's phenomenon in a case of Lymphohemangioma circumscriptum: A diagnostic clue representative of the Whimster hypothesis

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.
