Pigmented postacne osteoma cutis in a patient treated with minocycline: report and review of the literature.

Postacne osteoma cutis is a rare complication of acne vulgaris. If it occurs during a course of tetracycline or minocycline therapy, pigmented osteomas can occur as a result of tetracycline or minocycline bone complexes. We report a case of pigmented postacne osteoma cutis that developed after extensive acne surgery and a 2- to 3-month course of minocycline. Previously reported cases have been treated surgically, but our patient responded to 0.05% tretinoin cream, with transepidermal elimination of some osteomas.

Malignant schwannoma associated with xeroderma pigmentosum in a patient belonging to complementation group D.

A 43-year-old man with xeroderma pigmentosum, XP97TO, was allocated to complementation group D. He had had moderate photosensitivity at age 1 year and freckles by age 6 but no neurologic abnormalities. Nevertheless, his fibroblasts in culture had the XP-D phenotype. They showed a sevenfold hypersensitivity to killing by 254 nm ultraviolet radiation and a diminished level (29%) of unscheduled DNA synthesis. Phototesting revealed delayed maximum erythema at 72 hours after UVB exposure and a lowered minimal erythema dose. Lentigo maligna developed on the patient's face, and a rapidly growing malignant schwannoma was found on the left trigeminal nerve. This may be the first case of a peripheral nervous tissue neoplasm in xeroderma pigmentosum.

Reactive lentiginous hyperpigmentation after cryosurgery for lentigo maligna.

BACKGROUND: Twenty patients treated for lentigo maligna of the face with cryosurgery developed benign lentiginous hyperpigmentation mimicking a recurrence. OBJECTIVE: When cryosurgery is used in the treatment of lentigo maligna, it is important to know whether repigmentation of the scar represents true recurrence or a benign process. METHODS: Twenty patients were treated with cryosurgery for lentigo maligna of the face. Within a follow-up period of 7 to 80 months, frequent clinical observations were made. RESULTS: Lentiginous hyperpigmentation developed within the treatment area in eight patients. Histologic investigation revealed recurrence of lentigo maligna in three and benign hyperpigmentation in five. CONCLUSION: Genetic factors and UV exposure after cryosurgery may favor the development of benign lentiginous hyperpigmentation. Because recurrence of lentigo maligna must be considered, histologic evaluation of repigmentation is mandatory.

Temperature monitoring during photodynamic therapy of skin tumors with topical 5-aminolevulinic acid application.

Temperature monitoring during photodynamic therapy (PDT) with topical 5-aminolevulinic acid (ALA) cream application was performed on 22 patients with solar keratoses (SK) and basal cell carcinoma (BCC). The lesions were located on the forehead, nose, ear and cheek. Temperature measurements during photoirradiation, with a power density of 100 mW/cm2 from an incoherent light source (light delivery system for PDT), were carried out by noncontact (infrared thermal imaging radiometer) and contact (thermocouple) methods. Thermal imaging analysis revealed nonuniform temperature distribution in the irradiated areas. The temperature gradually increased from the peripheral to the central zone of the area. The results showed that photoirradiation induced heating of the skin tumors to 39.5-42.5 degrees C during the PDT procedure. The temperature of normal skin areas disposed symmetrically to the lesions on the contralateral side at the same conditions of irradiation (without prior ALA application) was about 42-43.5 degrees C. The surface temperature differences (delta T) between the normal and tumor tissues after 10 min of irradiation were 3.3 +/- 0.5 degrees C in the forehead areas, 2.5 +/- 0.4 degrees C in the nose areas and 0.8 +/- 0.3 degrees C in the ear areas.

Extensive actinomycosis of the face requiring radical resection and facial nerve reconstruction.

We present a case of extensive actinomycosis of the face, which appeared after dental surgery. Since antibiotic therapy was ineffective, the lesion was radically resected, and the skin, soft tissue and facial nerve were reconstructed using a free rectus abdominis musculocutaneous flap and simultaneously harvested intercostal nerves. Successful reanimation of the face was achieved 14 months postoperatively.

Prolonged evolution of a lentigo maligna.

Lentigo maligna (LM) is a melanocytic lesion which is a potential precursor to melanoma and often has a prolonged intraepidermal growth phase before evolving into lentigo maligna melanoma (LMM). LM is also noted for its tendency to locally recur after treatment. We present a patient who had a persistent LM on her left cheek which, despite multiple excisions, persisted and transformed into a partially amelanotic LMM roughly three decades later. Our patient's course was also notable for this melanoma recurring at the edge of, and subsequently migrating into, a previously placed skin graft.

Excision of subcutaneous facial cysts and lipomas using cosmetic approaches.

PURPOSE: The excisional biopsy of subcutaneoous facial cysts and lipomas can be problematic due to the high esthetic nature of the affected area. Remote scar placement has advantages in allowing access to subcutaneous pathology while placing incision lines in cosmetic locations. This article will review excisional biopsies of subcutaneous facial cysts and lipomas using cosmetic approaches. PATIENTS AND METHODS: Patients with superficial facial cysts or lipomas undergoing excisional biopsies utilizing contemporary cosmetic surgery approaches (rhytidectomy, lower blepharoplasty, and submental) with tumescent anesthesia and either intravenous sedation or general anesthesia. RESULTS: All patients had successful removal of superficial facial pathology with good cosmetic results. CONCLUSION: The use of contemporary cosmetic surgical approaches for the excisional biopsy of superficial facial cysts and lipomas provides adequate surgical access, a cosmetically acceptable result, and is well-tolerated by patients.

The use of botulinum A toxin to ameliorate facial kinetic frown lines.

PURPOSE: External photography and subjective response were used to evaluate the use of botulinum A toxin to diminish glabellar kinetic folds. METHODS: Eleven patients with glabellar folds and midline forehead wrinkling received one to four injections of 0.1 ml of 100 U/1 ml botulinum A toxin. The injections were given into the procerus or corrugator muscles or both. The number of injections corresponded to the wrinkle lines in each patient. The patients were examined and photographed just before the injections and at 7 to 10 days after the injections. Treatment efficacy was judged by photographic evaluation and by the patient's subjective evaluation of the effect of the treatment. RESULTS: Photographic evaluation showed objective improvement in the glabellar wrinkling in 6 of 11 patients in relaxed facial position and in all 11 patients during contraction of the periocular mulscles. Ten of the 11 patients reported satisfaction with their cosmetic results and indicated that they would choose to have the procedure done again. CONCLUSIONS: The results of this study suggest that botulinum A toxin is a safe and effective treatment for glabellar folds.

Syringoma presenting as milia.

We present two unrelated patients with numerous infraocular milium-like lesions that histologically revealed syringoma with many overlying keratin cysts in the papillary dermis. A Fontana-Masson stain revealed no melanin-containing cells in the keratin cyst walls, suggesting that they originated from eccrine ductal structures. A classification of the clinical variants of syringoma is presented.
