| Body Site: | arm | Age: | 42 years | ||
| Contributors: | Greg Hosler, MD, PhD Jamie Loveless | ||||
| Description: | Electron microscopy was performed, focused on the smooth muscle layer of a small arteriole. Extracellular osmiophilic granular material was identified in the region corresponding to the basal lamina. This material appears associated with degenerating organelles. | ||||
| Comments: | This 42-year-old man was referred to dermatology for a skin biopsy to look for characteristic electron micrograph findings. He presented with left-sided paralysis 7 years prior to presentation. Over time, he progressed to having migraine headaches, fatigue, numbness, loss of vision, incoordination, slurred speech, and a cerebral vascular accident. Skin biopsy supported the diagnosis of CADASIL disease, which stands for Cerebral Autosomal Dominant Arteriopathy and Subcortical Infarcts and Leukoencephalopathy. This disease is associated with NOTCH 3 gene mutations. Skin manifestations may include features similar to stasis changes and purpura, but some patients have no clinical findings, as in our case. Skin biopsy can show thickened, hyalinized vessels, and perhaps vascular proliferation with extravasated red blood cells, but these can be subtle. The diagnosis rests on identifying the gene mutation and/or finding the characteristic osmiophilic granular material in the basal lamina, as in our case. | ||||

| Body Site: | arm / back | Age: | 25 years | ||
| Contributor: | Majid Shahdi, MD | ||||
| Description: | groups of erythematous scaly follicular papules located on the extensor surface of both arms and upper back. Keratosis pilaris is a common skin condition can be seen in normal individuals and is associated with ichthyosis vulgaris and atopy and some less common disorders. Keratosis pilaris can be categorized as disorders of follicular keratinization. | ||||
| Comments: | Keratosis pilaris is a common disorder of follicular keratinization often seen in individuals with ichthyosis vulgaris. The extensor surfaces of the arms, thighs, and lateral aspects of the cheeks are most commonly involved, but the sandpaper-like papules are occasionally widely disseminated. Treatment is usually unrewarding, but keratolytics such as lactic acid or glycolic acid may help. | ||||

Impetigo is a highly contagious gram positive bacterial infection of the superficial layers of the epidermis.The nonbullous variety is the coommonest.The lesions develop on either normal or traumatized skin. | ||||
| Comments: | A 6-year-old boy developed confluent, crusted, purulent, exudative plaqeson his lip, chin, cheeks, and submental and submandibular areas with local lymphadenopathy. He was treated with antistaphylococcal antibiotics with prompt clearing of the eruption. | ||||

| Description: | Dog bites to back side of right arm. The wound closer to the elbow required 12 sutures, while the one lower on the arm required 6. Bite was made through a heavy sweatshirt which, no doubt, kept the wounds much less serious than they could have been. Patient presented with two bites gaping with fatty tissue hanging out of them. Bleeding had lessened considerably in the approximately 10 minutes from time of attack until arrival at the medical facility where injuries were treated. Patient was sutured, given a tetanus shot and a 7 day supply of Keflex, to be taken 3 times a day. Patient was expected to heal with no resultant side effects other than pain lasting several days and possible scarring. | ||||
| Comments: | This jagged laceration near the elbow resulted from a dog bite through a heavy sweat shirt and required 12 sutures to close. The patient was also treated with a tetanus booster and a 7 day course of oral cephalexin. | ||||

| Description: | Acquired reactive perforating collagenosis: 79 years old female patient with associated long stading diabetes presented generalized pruritus and papular euption localized at the limb | ||||
| Comments: | A 79-year-old woman with long standing diabetes mellitus developed chronic minimally pruritic hyperkeratotic red 2-5 mm papules on her legs. A biopsy showed a plug of necrobiotic, deeply basophilic collagen in the papillary dermis typical of reactive perforating collagenosis. This disorder is one of the acquired perfirating dermatoses that occurs in a rare autosomal dominant form beginning in childhood and more common acquired variant in patients with diabetes and chronic renal failure. | ||||
