We report an 8-year-old girl affected by hypochromic, asymptomatic, acquired lesions with a paving-stone aspect on the right lumbosacral area and proximal right leg. The results of serum and urine biochemical screening were normal, as was the bone survey A biopsy was performed. The clinical and histologic aspects led to the diagnosis of connective tissue nevus with zosteriform distribution.
"Five cases of zosteriform CTN have been reported in the English literature1,3-6 (Table 1). Similar to our case, three of them were zosteriform CTN involving more than two segments of skin3,5,6. Asano et al.13 also reported on a case of multiple CTN distributed as multiple linear streaks, however, it was along Blaschko lines, and unrelated to dermatomal lines. "
[Show abstract][Hide abstract] ABSTRACT: Connective tissue nevus is not a true tumor, but rather a hamartoma involving various components of connective tissue. It presents as a slow-growing, painless, flesh-colored, or pink nodule or plaque that is evident from childhood. While any region of the body may be affected, there is a predilection for the trunk and extremities. A 20-month-old girl presented with three ipsilateral confluent popular plaques with zosteriform distribution that had formed over the previous 17 months on the left chest and abdomen. The patient remained asymptomatic. Unlike all previously reported cases demonstrating a single lesion, we report a connective tissue nevi in a child who presented with multiple unilateral zosteriform lesions, an unusual pattern of distribution without evidence of tuberous sclerosis complex.
