Morphea is a rare connective tissue disorder. Hardening and thickening of the skin due to an increased density of collagen are its characteristic features.(1) It has been classified into plaque or circumscribed, linear, generalized, morphea profunda (deep), pansclerotic and combined forms with wide clinical presentation.(2) Zosteriform morphea (ZM), which is described as a dermatomal distribution of lesions like herpes zoster clinically, is a rare entity. Most of them have been described on the same area of preceding herpes zoster infection as Wolf’s isotopic response.(3,4) In this article, we report a case with usual morphea diagnosed histopathologically at unusual location without history of herpes zoster infection. An 18-year-old healthy, male patient presented with complaints of hardness and discoloration of the skin at the right posteroinferior side of his trunk with a zosteriform distribution of T10-12 dermatomes, over a period of two years. We detected no characteristic finding in his medical/family history and physical examination except indurated plaque that measured 9x6 cm in diameter with central hyperpigmentation among the xyphoid and umbilicus that extended to the lateral part of the trunk with atrophic lesions in a zosteriform distribution (Figure 1). We detected no history of herpes zoster or other skin lesions on the site of ZM, abnormal skin moisture, suggestive signs of other extracutaneous, musculoskeletal or systemic sclerosis. Serology for varicella-zoster Although trauma(9) and previous infection (Borrelia burgdorferi10) may incite morphea, the definitive etiology of morphea is not known. We do not know the reason of zosteriform distribution of morphea, but any neurogenic stimulation may be the cause of dermatomal distribution. Consequently, we presented this case with usual morphea diagnosed with histopathology and of which the location of morphea was unusual and worth to report.
