Basal cell carcinoma and rhinophyma.
    Annals of plastic surgery, 2008, Volume: 61, Issue:4

    Rhinophyma, the end stage in the development of acne rosacea, is characterized by sebaceous hyperplasia, fibrosis, follicular plugging, and telangiectasia. Although it is commonly considered a cosmetic problem, it can result in gross distortion of soft tissue and airway obstruction. Basal cell carcinoma (BCC) is a rare finding in patients with rhinophyma. The objective of this study is to review the literature of BCC in rhinophyma and report on a case. A 70-year-old male presented with long-standing rosacea that resulted in a gross nasal deformity. The patient suffered from chronic drainage and recurrent infections that failed conservative treatment with oral and topical antibiotics. The patient decided to proceed with surgical intervention and underwent tangential excision and dermabrasion in the operating room. Since 1955 there have been 11 cases reported in the literature. In our case, the pathology report noted that the specimen had an incidental finding of a completely resected BCC. The patient did well postoperatively and at follow-up remains tumor-free. Despite the uncommon occurrence of BCC in resection specimens for rhinophyma, we recommend that all specimens be reviewed by a pathologist. If BCC is detected, re-excision may be necessary and careful follow-up is mandatory. Larger studies would be needed to determine the correlation between the 2 conditions.

[Our experiences with the frontal flap. Apropos of 105 cases].
    Revue de stomatologie et de chirurgie maxillo-faciale, 1998, Volume: 98, Issue:6

    The plastic qualities and vascular reliability of the frontal flap have been widely used for reconstruction of facial tissue. We revised the files of 105 patients who had undergone surgical repair of facial tissue loss with frontal flaps. The epidemiology, etiology of the repaired tissue loss and indications for frontal flap as well as the various techniques were analyzed: 66.7% of the patients were over 60 years of age; 74% had ambulatory surgical repair; 54.4% of the repaired tissue losses were situated in the nasal region; 80% of the losses were due to tumoral formations. The median flap was the most widely used (23.2%).

[Midfacial degloving: an alternative approach to the frontobasal area, the nasal cavity and the paranasal sinuses].
    Laryngo- rhino- otologie, 1992, Volume: 71, Issue:8

    Midfacial degloving can be characterized as an alternative surgical approach for exposing the bony structures of the midface. In combination with transient partial osteotomies the nasal cavities, the paranasal sinuses, the pterygopalatine fossa and the posterior parts of the anterior skull base are easily accessible. Using an intercartilaginous, a transseptal and a circumvestibular incision in the nose and a vestibular incision in the oral cavity the soft tissues of the upper face are mobilized and transposed cranially up to the infraorbital rim, the nasion and the lacrimal sac. Thus one can avoid scar formations in the face. In comparison with the common visible incisions in the face a bilateral exposure of midline structures is possible. The resected bone can be easily replaced and fixed with titanium miniplates for osteosynthesis. The soft tissue glove is replaced. A correct suture technique for readaptation especially in the nasal cavity is most important to avoid a circular stenosis of the nasal aperture. Between 1986 and 1991, 40 patients with various tumors (juvenile angiofibroma, inverted papilloma, esthesioneuroblastoma, squamous cell carcinoma of the maxillary sinus, benign tumors of the pterygopalatine fossa, clivus chordoma) underwent this procedure. Neoplasms and fractures of the anterior frontal skull base, the frontal sinus, the orbital cavity and the zygoma were less accessible due to the unsatisfactory exposure of these regions. Complications and side effects were rare. In five cases, a transient paresthesia of the infraorbital nerve and a facial edema were observed. In one case, a circular stenosis of the nasal aperture required a second plastic procedure.(ABSTRACT TRUNCATED AT 250 WORDS)

A histopathological study of 643 cutaneous horns.
    The British journal of dermatology, 1991, Volume: 124, Issue:5

    A retrospective study of 643 cutaneous horns examined in our department between 1970 and 1989 revealed that 38.9% were derived from malignant or premalignant epidermal lesions, and 61.1% from benign lesions. Four main features were associated with premalignant or malignant histopathological change at the base of a cutaneous horn (base pathology). These were: (i) age--the mean age of the patients whose cutaneous horns showed premalignant or malignant base pathology was 8.9 years greater than the mean age of the patients where base pathology was benign (P less than 0.0005); (ii) sex--males were more likely to develop a cutaneous horn with (pre)malignant base pathology (P less than 0.001); (iii) site--over 70% of all (pre)malignant lesions were found on the nose, pinnae, backs of hands, scalp, forearms and the face; a cutaneous horn found at these sites was 2.1 times more likely to have derived from a (pre)malignant base than from any other part of the body (P less than 0.0001); (iv) geometry of the lesion--lesions with a wide base or a low height-to-base ratio were significantly more likely to show (pre)malignant base pathology. Of those solar keratoses giving rise to cutaneous horns, 8.9% also showed histological evidence of change to squamous cell carcinoma (SCC); this figure was not significantly different from the 6.2% of solar keratoses without horns that showed SCC change during the same period (1970-89).

Electron microscopy findings in malignant melanoma of nose.
    ORL; journal for oto-rhino-laryngology and its related specialties, 1975, Volume: 37, Issue:4

    Electron microscopic examination of malignant melanoma tumour tissue taken from a patient who has survived with the tumour without metastases for 13 years has shown spherical melanosomes with no internal fibrillar structure. This finding and other cell features described, suggest that this melanoma developed from Dubreuilh's melanosis rather than melanocytic change in a junctional naevus.
