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.

DRESS syndrome is an uncommon but potentially life-threatening subset of severe drug eruption characterized by fever, rash, leukocytosis with eosinophilia or atypical lymphocytosis, lymphadenopathy, and liver or renal dysfunction. The aromatic anticonvulsants (phenytoin, phenobarbital, carbamazepine) and sulfonamides are the most common cause of DRESS syndrome. Valproic acid, which is a widely used non-aromatic anticonvulsant, rarely causes DRESS syndrome. We report a case of DRESS syndrome in 47-year-old man caused by the use of valproic acid.

The superficial variant of morphea is a recently described as an entity that differs in its clinical and histologic presentation from classic morphea. The condition is characterized by minimal to no induration and hypopigmented or hyperpigmented patches, without associated symptoms, systemic involvement, contractures, or atrophy. Histologically, it shows thickened collagen bundles, which restricts to the superficial dermis, sparing the deep dermis and without associated evidence of lichen sclerosus et atrophicus. We present the unique clinical and histopathologic findings in 4-year-old children.

Syringomas are common benign adnexal tumors, probably of the eccrine origin. They are more common in women and usually found around the eyelids. An exclusively acral site of the lesions is very rare. We present a case of acral syringomas in a 44 year-old woman, involving only the dorsum of the fingers of both hands. It is important to include syringomas in the clinical differential diagnosis of papular lesions of the hands.

Pyoderma gangrenosum (PG) is a rare and painful skin disease, frequently associated with underlying systemic conditions, such as inflammatory bowel disease or hematological malignancy. PG is generally classified into 4 types: classic (ulcerative), bullous, pustular, and vegetative. Pustular PG is an uncommon variant of PG that the pustules do not progress to form ulcers. We report a case of pustular PG, which was successfully treated with infliximab and topical tacrolimus, in a 28 year-old Korean man with ulcerative colitis.

Perivascular epithelioid cell tumors (PEComas) are a rare, recently described group of mesenchymal tumors, which is composed of distinctive perivascular epithelioid cells. Primary cutaneous PEComas are composed of focally nested or trabecularly arranged groups of epithelioid cells with clear to eosinophilic cytoplasm and round to oval nuclei with obvious nucleoli. Here, we describe the case of a 27-year-old Korean man who was presented with a solitary, cutaneous nodule on his left popliteal fossa. Physical examination revealed a solitary, 1.2x1.0 cm-sized erythematous protruding nodule on his left popliteal fossa. Immunohistochemical evaluation showed that the epithelioid tumor cells were positive for HMB-45 and desmin. These clinical and histological findings were consistent with a diagnosis of primary cutaneous PEComa.
