Nevus spilus, also known as speckled lentiginous nevus, is a relatively common cutaneous lesion that is characterized by multiple pigmented macules within a pigmented patch. It may be congenital or acquired, and it can show the histological features of congenital melanocytic nevus (CMN). The possible relationship between nevus spilus and CMN has been contentious. We report a case of a congenital nevus that followed the line of Blaschko and clinically manifested as nevus spilus, but showed the histological features of CMN.

Nodular fasciitis is a benign, reactive, myofibroblastic, proliferative process of unknown etiology. It presents as a solitary, painless, rapidly-growing nodule over several weeks` duration. The condition is self-limiting, and proper diagnosis is essential to avoid unnecessary aggressive treatment. Diagnosis is often a challenge because nodular fasciitis may be confused with a malignant tumor due to its aggressive clinical behavior and histological features. It is most commonly located on the extremities and then the trunk. Such lesions also usually occur in middle age and are rarely diagnosed in childhood. We report a case of recurrent nodular fasciitis that arose from subcutaneous tissue on the back of a pediatric patient. (Korean J Dermatol 2006;44(12):1457~1459)

Primitive neuroectodermal tumors (PNETs) are malignant, round-cell sarcomas which exhibit primitive neuronal differentiation. They usually arise in deep soft tissues, but occasionally bones and visceral organs are affected. In general, PNET presents as rapidly-growing, deeply located masses measuring 5~10 cm at their greatest diameter. Superficially located cases do occur but are rare. The typical PNET is composed of sheets or lobules of small round cells containing darkly-staining, round or oval nuclei. The cytoplasm is indistinct except in areas where the cells are more mature and elongated hair-like cytoplasmic extensions coalesce to form rosettes. We herein report a case of PNET that arose from subcutaneous tissue of the buttock in a 31-year-old woman. (Korean J Dermatol 2007; 45(3):275~278)

Fibroelastolytic papulosis is proposed as the diagnostic term for cases previously identified as pseudoxanthoma elasticum-like papillary dermal elastolysis and white fibrous papulosis of the neck. Clinical presentation of fibroelastolytic papulosis is asymptomatic to mildly pruritic whitish-yellow papules that may coalesce into cobblestone-patterned plaques resembling pseudoxanthoma elasticum. Histology is characterized by normal, decreased, or absent elastic fibers in the papillary dermis sometimes accompanied by a thickening of collagen fibers. We report a 60-year-old woman with flesh to yellowish colored papules with cobblestone appearance, which were histologically consistent with fibroelastolytic papulosis.
