Surgical management of a dermal lymphatic malformation of the lower extremity.

Dermal lymphatic malformations are rare congenital hamartomas of superficial lymphatics characterized by high recurrence rates after excision. The standard therapy for a single lesion is surgical excision with wide margins, which reduces recurrence but can have a potentially unacceptable aesthetic outcome. A case of a 24-year-old woman with a 6 cm x 5 cm dermal lymphatic malformation on her right thigh, diagnosed by clinical history, physical examination, magnetic resonance imaging and pathological findings, is reported. The patient underwent wide local excision with split-thickness skin grafting. After pathological examination revealed negative margins, the patient underwent tissue expander placement and excision of the skin graft with primary closure. The lesion did not recur, and the patient achieved a satisfactory aesthetic result. The present case represents the first report of the use of tissue expanders to treat dermal lymphatic malformations in the lower extremity and demonstrates a safe, staged approach to successful treatment.

Topical treatments for hypertrophic scars.

Hypertrophic scars represent an abnormal, exaggerated healing response after skin injury. In addition to cosmetic concern, scars may cause pain, pruritus, contractures, and other functional impairments. Therapeutic modalities include topical medications, intralesional corticosteroids, laser therapy, and cryosurgery. Topical therapies, in particular, have become increasingly popular because of their ease of use, comfort, noninvasiveness, and relatively low cost. This review will discuss the properties and effectiveness of these agents, including pressure therapy, silicone gel sheeting and ointment, polyurethane dressing, onion extract, imiquimod 5% cream, and vitamins A and E in the prevention and treatment of hypertrophic scars.

Henoch-Schönlein purpura associated with malignancy in adults.

Malignancy is a well-known cause of cutaneous vasculitis. The occurrence of neoplasia and Henoch-Schönlein purpura (HSP) is rare and poorly understood in adults. A total of 31 cases have been reported in the world literature of adult malignancy-associated HSP. Patients were overwhelmingly male (94%) with a mean age of 60 years and presented predominantly with solid tumors (61%). The most frequent tumors were lung (nonsmall-cell) (n = 8), multiple myeloma (n = 5), prostate (n = 5), and non-Hodgkin's lymphoma (n = 3). The majority of patients (55%) developed HSP within 1 month of cancer diagnosis or detection of metastases. We present 3 cases of adults who, in the absence of known precipitating factors, developed HSP within 2 months of diagnosis of a solid tumor or metastases. We recommend that adults, especially older men who present with unexplained HSP, be evaluated for occult neoplasm. We also advise that patients with a known history of malignancy who present with HSP be evaluated for metastatic disease.
