Aplasia cutis congenita is a rare disorder characterized by localized or generalized absence of skin at birth. The various hypothesis and classification are proposed. Type V in Frieden's classification, which is associated with fetus papyraceus or placental infarcts, occurs as a large cutaneous defect on the trunk and extremities. We experienced the patient had skin defect affecting the lower abdomen symmetrically, with no family history of the any disorders or chromosomal anomalies and associated anomalies. A twin fetus was died in utero. We report a case of aplasia cutis congenita associated with fetus papyraceus with the review of the associated literatures.

Heterotopic brain tissue is defined as displaced neuroglial tissue that has no connection with the central nervous system. As there is no communication with underlying structures, serious anomalies rarely occur. A 6-year-old Korean male presented an erythematous, non tender nodule measuring 1.5X1.5X0.5cm on right parietal scalp since birth. The lesion was covered with thickened alopetic skin. There was no neurologic defect. The mass was not connected with intracranial structures on a magnetic resonance imaging.

Jellyfish dermatitis was characterized by purpuric papules or tiny vesicles arranged linearly with a color ranging from pink to red to brown. A 24-year-old woman presented with multiple whiplash-like erythematous lesions of 5-hours duration on both legs after contact with a jellyfish at a Korean seashore.

PURPOSE: A common finding of carotid artery on magnetic resonance angiograms(MRAs) is a signal dropout along the posterior wall of carotid bulb due to reverse flow. The purpose of this study is to evaluate variable flow patterns on bifurcated carotid arterial phantoms using steady-state flow. MATERIALS AND METHODS: We designed phantoms of a bifurcated carotid artery with acrylic materials. Flow patterns were evaluated with axial and coronal imaging of MRA(2D-TOF, 3D-TOF), color Doppler imaging, and computational fluid dynamics (CFD) within the phantoms constructed of an automated closed-type circulatory system filled with 4% sugar solution. These findings were compared with findings obtained from normal volunteers. RESULTS: Axial 3D-TOF MRA images exhibited closer resemblance to the contour of the inner wall of phantoms when compared to coronal 2D-TOF MRA imaging. However, 2D-TOF MRA showed good contrast difference of signal intensities between forward flow area and reverse flow area. Dark zones with reduced signal intensities due to reversed flow were separated from the outer wall of the internal and external carotid arteries by a thin layer of forward flow along the wall on the source slice image of MRA. The general hemodynamics of the phantoms on MRA were identical to hemodynamics on color Doppler imaging and CFD. The results obtained with the phantoms matched the findings on normal volunteers. CONCLUSION: Although representations of bifurcated carotid arterial phantoms on axial 3D-TOF MRA were excellent if ideally desinged, the zone of reversed flow could be a significant factor in creating distorted image when the zone of reversed flow contacted directly with curved or deformed arterial wall.

Cystic basal cell carcinoma is an uncommon histologic variant of basal cell carcinoma. Degeneration of tumor cells causes cystic space, in which mucin is secreted from the adjacent tumor cells. We report a case of cystic basal cell carcinoma with prominent cystic formation occurring in a 52-year old women on the right cheek.

Sinusoidal hemangioma is a rare variant of deep hemangioma. Clinically it develops in adults, predominantly females, and presents as a painless, bluish, solitary, deep dermal or subcutaneous nodule. Histologically they are characterized by a well-circumscribed lobulated architecture composed of dilated interconnecting, thin-walled vascular channels that frequently show a pseudopapillary pattern and a back-to-back arrangement with scanty intervening stroma. We report an unusual case of sinusoidal hemangioma, which showed polypoid growth on the trunk of a 39-year-old male.

Lichen striatus is a self limited, papulosquamous disorder with a linear distribution. The linearity has been shown to correspond in many cases to the pattern of Blaschkos lines. Lichen striatus can usually be identified by clinical features and histology. However, the histologic features are diverse and some are nonspecific. We present the rare case of lichen striatus which shows multinucleated giant cells in upper dermis with microscopy.
