Dirofilarial infection presenting as a facial mass: case report of an emerging zoonosis.

Dirofilariasis is a parasitic infection caused by nematodes. Human infection remains rare but is increasing in scope, particularly in endemic areas. Dirofilariasis typically presents as a subcutaneous mass or with pulmonary nodules. Here, we present the case of a 73-year-old woman whose asymptomatic facial mass was caused by dirofilarial infection. The pathophysiology, diagnosis, and treatment of dirofilariasis of the head and neck will be discussed. In endemic areas, dirofilariasis must be considered in the differential diagnosis of facial masses.

[Cutaneous necrosis in a clinical case of one face lift after the use of Surgicel].

The use of Surgicel, a local haemostatic absorbable gauze, is usually spread in surgery. The author reports a clinical case of face lift where the use of Surgicel 2, a more concentrated Surgicel, left under a precarious vascularized cutaneous flap led to a skin slough. He concludes that the full-thickness cutaneous necrosis is bound both to the chemical action of the soluble component (uronic acid) of Surgicel and above all to the "screen-effect" with the nourishing basement. Consequently, the Surgicel should be removed once the haemostasis obtained.

Five cases of rhinocerebral mucormycosis.

Rhinocerebral mucormycosis is a rare and often fatal fungal infection in immunocompromised patients. We encountered three women and two men with diabetes and mucormycosis in a period of 4 years. Two of the patients died.

Lasers in contemporary oral and maxillofacial surgery.

The practice of oral and maxillofacial surgery has included the use of lasers since the 1960s. Over the past few decades, the use of lasers among oral and maxillofacial surgeons has grown dramatically. Their evolution within the specialty not only has enhanced current surgical options for treatment, but also contributed to a variety of new procedures that are now commonplace in oral and maxillofacial surgery. The management of patients with sleep apnea, temporomandibular joint derangements, dental implants, premalignant lesions, and posttraumatic facial scarring has improved significantly with the advent of laser surgery. As the number of laser systems grows and their technology becomes more advanced, a thorough understanding regarding the principles of their use is paramount to providing safe and effective patient care.

A cosmetic approach to cutaneous defects.

The options available to cosmetic surgeons for the treatment of the aging face are expanding at a rapid pace. Although any one modality may help, often a combination of approaches provides the most dramatic results. Whereas some of these techniques represent refinements of old tools, others represent entirely new modalities (Box 1). To tailor the most effective treatment plan appropriately, the limitations and strengths of these various tools must be understood by the patient and physician. During the preoperative consultation, assessment of a patient's expectations is critical when suggesting a treatment plan. By performing an assessment, the physician and patient can experience increased satisfaction because more optimal results are achieved.

Ablative facial resurfacing.

Ablative resurfacing is a powerful tool for rejuvenation of the aging face and for the treatment of a wide array of skin lesions. In the proper hands, it is a safe and effective way to treat many of the problems of photodamaged skin that surgery or nonablative methods cannot address. This article discusses the three most common modalities used in ablative facial resurfacing: chemical peels, dermabrasion, and laser resurfacing. Indications, mechanism of action, techniques, results, and complications all are reviewed.

Aminolevulinic acid photodynamic therapy for sebaceous gland hyperplasia.

Current therapies for sebaceous hyperplasia (SH) have a high risk for adverse effects and recurrence of treated lesions. The theoretic basis for the treatment of SH by photodynamic therapy (PDT) with 5-aminolevulinic acid (ALA) has been established. Studies show that 1 hour is sufficient ALA incubation time to achieve clearance, and ALA-induced protoporphyrin IX may be activated with a 585-nm pulsed dye laser device, blue light source, or an intense pulsed light device. Complete clearance may be achieved with one to six treatments; however, long-term recurrence rates are not established. ALA PDT is a safe and effective modality for the treatment of SH lesions of all sizes.

Methyl aminolevulinate: actinic keratoses and Bowen's disease.

Topical photodynamic therapy (PDT) using the methyl ester of 5-aminolaevulinic acid (MAL) is an effective therapy for actinic keratoses and Bowen's disease. Thin and moderate thickness facial actinic keratoses respond best, with clearance rates equivalent or superior (depending on protocol) to current therapy, and with notably superior cosmetic outcome. Patients with areas of field cancerization and organ transplant recipients may particularly benefit from topical MA-PDT. The response rate of Bowen's disease to MAL-PDT is also at least equivalent to cryotherapy and 5-fluorouracil, again with superior cosmesis. Patients with large or multiple lesions of Bowen's disease or those in whom standard therapy, including surgery, is relatively contraindicated may particularly benefit from PDT.

Epithelial and mesenchymal hamartomatous changes in a mature port-wine stain: Morphologic evidence for a multiple germ layer field defect.

The port-wine stain (PWS) is a congenital cutaneous venulocapillary malformation of unknown pathogenesis. Many patients with facial PWS develop thickening with cobblestoning and nodularity during adult life. The histologic correlates of this maturational change are poorly documented and its mechanisms remain unclear. In this case study we present new histologic observations that may elucidate this phenomenon. An extensive PWS on the face of a 75-year-old man exhibited gross thickening with cobblestoning and nodularity. Histologic examination revealed not only the expected vascular abnormalities, but also a number of widely distributed epithelial, neural, and mesenchymal hamartomatous changes. Epithelial changes included epidermal nevus, sebaceous trichofolliculoma, and basaloid follicular hamartoma. Changes of connective tissue nevus, smooth-muscle hamartoma, neural hamartoma, and subcuticular hamartoma were also noted. The complex hamartomatous changes observed in the PWS of this patient involved multiple germ lines and were distributed in a widespread pattern. These changes not only offer an explanation for the skin thickening and nodularity of this patient, but also suggest a genetically determined, multilineage developmental field defect in the pathogenesis of this lesion. Further studies of other patients are necessary to understand the full implications of these findings in the late stage of PWS.
