Eruptive collagenoma is an acquired connective tissue nevus without family history. It is typically described as numerous small papules or nodules on the trunk and arms with histopathological features of decreased or degenerated elastic fibers. We report a case of a 16-year-old male who presented with multiple asymptomatic 2 to 5 mm sized yellowish grouped papules on the left calf. Histopatholo...

Eruptive xanthomas are cutaneous manifestations of hyperlipidemias in which lipids accumulate in large foam cells within the skin. They classically present as crops of 1- to 4-mm yellow-orange papules and are often associated with extreme hypertriglyceridemia. We describe a 12-year-old boy with autism who was thought to have widespread molluscum contagiosum for a year before dermatologic consul...

Developing teeth in the Vervet monkey (Cercopithecus aethiops) were examined at various pre-eruptive stages. A longitudinal arrangement o f periodontal fibres was seen grouped alongside the hone and cementum and parallel to them. These fibres later ex­ tended coronally, passing around the reduced enamel epithelium. It was difficult to compare this study to other species as there were difference...

Multiple pilosebaceous cysts include the entities of steatocystoma multiplex and eruptive vellus hair cysts (EVHCs). Multiple pilosebaceous cysts are proposed to be one entity originating in the pilosebaceous duct, since steatocystoma multiplex and EVHCs are frequently present concomitantly and are caused by a cystic change in the same pilosebaceous duct. Here, we describe a patient with yellow...

BACKGROUND Tumor of the follicular infundibulum (TFI) is considered as a rare benign neoplasm providing two distinctive clinical patterns: the solitary and the eruptive form. The clinical presentations resemble many other dermatologic conditions and require histopathological study to make a definite diagnosis. OBJECTIVE To inform physicians of a clinical presentation of TFI. CASE REPORT We ...

Cutaneous squamous cell carcinoma of the head and neck is an invasive skin cancer with significant morbidity and mortality, chiefly among older and immunocompromised patients. We present a case report of a patient without obvious immune suppression developing multiple, eruptive cutaneous squamous cell carcinomas of the scalp. Despite multiple excisions, radiotherapy and adjuvant oral retinoids,...

Sebaceous hyperplasia, a benign proliferation ofsebaceous glands, has been well documented in organ transplant recipients treated with cyclosporine. Sebaceous hyperplasia has not been strongly associated with any other immunosuppressive medications. We report a case of eruptive sebaceous hyperplasia in a renal transplant recipient with no previous exposure to cyclosporine that was recently star...
