Acral syringomas presenting as a photosensitive papular eruption.

A 43-year-old woman presented with a recurrent and remitting eruption of reddish-brown papules in the sun-exposed areas of the arms and forearms that had been present for 2 years. Results of a histopathologic examination revealed syringoma. To the best of our knowledge, this is the first case report of syringomas confined to sun-exposed areas with a recurrent and remitting course over time. We also review the literature on acral syringomas.

Imiquimod: an effective alternative for the treatment of invasive cutaneous squamous cell carcinoma.

BACKGROUND: Some patients with invasive cutaneous squamous cell carcinoma are either not adequate surgical candidates or present with lesions in cosmetically sensitive areas in which a surgical procedure might result in an apparent and/or a cosmetically unacceptable scar. OBJECTIVE: To evaluate the effectiveness of imiquimod 5% cream in the treatment of an invasive squamous cell carcinoma in the nose of a young man. METHODS: Imiquimod 5% cream was applied to the lesion five times a week for 12 weeks. RESULTS: Complete clinicopathologic tumor clearance and an excellent cosmetic result were achieved after 12 weeks of imiquimod treatment. CONCLUSION: Imiquimod 5% cream may represent a reasonably effective alternative for the management of invasive squamous cell carcinoma in selected patients.

Octyl-2-cyanoacrylate liquid bandage as a wound dressing in facial excisional surgery: results of an uncontrolled pilot study.

BACKGROUND: Although cyanoacrylate tissue adhesives are frequently used in the closure of cutaneous lacerations and excisions, only a few reports comment on their usefulness as a dressing over sutured wounds. A new formulation of octyl-2-cyanoacrylate (Liquid Bandage; BAND-AID, Johnson & Johnson) is used as an occlusive protective film over minor cuts and scrapes. OBJECTIVE: An uncontrolled pilot study to assess the safety, efficacy, and cost of Liquid Bandage as an occlusive dressing over sutured facial excisions. METHODS: Patients undergoing excision of facial neoplasms were recruited. After conventional layered repair, Liquid Bandage was applied. On suture removal, the wounds were photographed and evaluated by three dermatologists, who assigned an overall outcome rating. The average cost of Liquid Bandage and routine wound care materials was calculated based on prices from three different pharmacies. RESULTS: Of the 18 wounds available at follow-up, 17 were assigned an overall outcome rating of good or excellent by at least one of the evaluators. Eleven wounds received an excellent rating from at least two of the evaluators. One case of distal flap necrosis occurred. Liquid Bandage proved to be less expensive than routine postsurgical wound care materials. CONCLUSIONS: Liquid Bandage dressing is safe and effective over sutured facial excisions.

Successful treatment of persistent melanoma in situ with 5% imiquimod cream.

BACKGROUND: Five percent imiquimod cream, a topically applied immune response modifier with potent antiviral and antitumor activity, has been reported to be effective in the management of lentigo maligna and cutaneous metastases from melanoma. OBJECTIVE: We report a case in which 5% imiquimod cream was effective in the management of a persistent melanoma in situ. METHODS: Five percent imiquimod cream was applied to the affected area twice to three times a week, as tolerated. RESULTS: After 4 months of treatment, repeated biopsies of the previously affected areas showed complete regression of the melanoma. CONCLUSION: Treatment of melanoma in situ of sun-damaged areas with 5% imiquimod cream certainly appears warranted in selected cases where surgical procedures have failed or are not feasible owing to factors such as size and/or localization of the lesion, advanced age, or deteriorated medical status of the patient. Rigorous posttreatment follow-up is mandatory, because long-term recurrence rates after treatment of melanoma in situ with imiquimod are yet unknown.

Granular parakeratosis.

This is a report of a 60 year-old black female patient presenting with pruritic brownish crusted plaques on both axillae of one month evolution. Histopathology revealed findings characteristic of axillary granular parakeratosis. This entity was first described by Northcutt et al in 1991. Since then, involvement of other intertriginous areas have also been reported. A review of the literature was performed and the term granular parakeratosis is suggested to emphasize its pathognomonic histopathologic features.

New insights into imiquimod's mechanisms of action.

Imiquimod, an immune response modifier with potent antiviral and antitumor properties, has been reported to be effective in the treatment of various cutaneous neoplasms. Besides stimulating the production of pro-inflammatory cytokines through Toll-like receptors on the surface of dendritic cells of monocyte-macrophage lineage, novel antiapoptotic mechanisms have been identified.
