We report a case of infantile myofibromatosis in a male infant with involvement of the lungs and subcutaneous tissue. We studied our case by light microscopy, immunohistochemistry and electron microscopy. The results reveal that this entity is of a myofibroblastic nature. We reviewed 165 cases including our case. We believe this is the first report in Korea of infantile myofibromatosis with pulmonary involvement.

OBJECTIVETo investigate injury to epidermal melanocyte by Q-switched Alexandrite laser.
METHODSMultiple biopsies were performed on 5 patients with nevus of Ota from before irradiation to 1 year after irradiation. Fourteen specimens were obtained for light microscopy, and 17 for transmission electron microscopy.
RESULTSMelanosomes in epidermal melanocytes were both smaller in size and fewer in number than those in dermal melanocytes. Immediately after irradiation, focal extracellular vacuoles of the basal layer could be observed under light microscopy. Most epidermal melanocytes underwent mild or moderate injury in the form of vacuolated melanosomes, swollen mitochondria, dilation of endoplasmic reticulum, and expansion of extracellular space, retaining intact cell membranes. Normal structures were restored 5 months to 1 year after irradiation, with no depigmentation or hyperpigmentation as seen by light microscopy.
CONCLUSIONInjury of melanosomes in epidermal melanocytes is reversible.

Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare subtype of cutaneous lymphoma. There have been a few case reports describing the radiologic imaging findings of SPTCL. We report a case of SPTCL, rarely presented with a breast mass. Here, we review her clinical history and radiologic (mammography and ultrasound) findings.
