The authors reviewed the clinical and histopathologic features of 32 patients with cutaneous malignant melanoma of the eyelid. The lower eyelid was more frequently the site of origin than the upper eyelid (21 patients, 66% of cases). A clinical diagnosis of melanoma was made in only 2 of 13 patients (15%) for whom the clinical diagnosis was listed. Clinical findings of pigmentation, ulceration/hemorrhage, or growth were documented in 25 (78%) patients. The histopathologic classification of the melanomas included nodular (19 patients, 59%), superficial spreading (7 patients, 22%), and lentigo maligna (6 patients, 19%). Associated histopathologic findings included solar elastosis (13 patients, 41%), nevus (12 patients, 38%), and basal cell carcinoma (4 patients, 13%). One of eighteen patients with follow-up data available died of metastatic melanoma.

Of 22 orbital exenterations performed from January 1980 to December 1989, 16 were performed by an eyelid-sparing technique, and six were allowed to heal by spontaneous granulation. Reviewing these procedures, we conclude that the eyelid-sparing method is indicated mainly for advanced primary orbital malignancies and for certain secondary orbital malignancies such as orbital extension of uveal melanoma, conjunctival melanoma, and conjunctival squamous cell carcinoma. It is not usually applicable to orbital invasion of malignant eyelid tumors such as basal cell carcinoma and sebaceous gland carcinoma. Advantages of the eyelid-sparing method are more rapid healing and earlier fitting of a prosthesis.

To estimate the magnitude of nonmelanoma skin cancer mortality and describe its parameters, we reviewed the medical records of all deaths certified as due to this cause among Rhode Island residents from 1979 through 1987. After excluding acquired immunodeficiency syndrome-associated Kaposi's sarcoma, we confirmed that nonmelanoma skin cancer was the cause of death for 51 individuals, a quarter of the number of melanoma deaths reported. The age-adjusted nonmelanoma skin cancer mortality rate was 0.44/10(5) per year. Fifty-nine percent were due to squamous cell carcinoma, and 20% were due to basal cell carcinoma. Most appeared actinically induced. Among deaths from squamous cell carcinoma, the mean age was 73 years. At least 80% of the squamous cell carcinomas metastasized, and 47% arose on the ear. None appeared due to refusal of treatment. Among deaths from basal cell carcinoma, the mean age was 85 years, and refusal of surgical intervention was documented in 40%. Study of nonmelanoma skin cancer mortality provides for estimation of the magnitude of this problem, complements other studies of prognosis, and helps guide prevention, early detection, and treatment.

To evaluate the possible association of other malignancies with basal cell carcinoma, we reviewed 1973 consecutive patients with basal cell carcinoma. We searched the Swedish Cancer Registry for records reporting malignancies in the study population (1958-1984) and the expected number of malignancies was calculated on the basis of age- and sex-standardized incidence data. In 452 patients with basal cell carcinoma another malignancy was diagnosed. The expected number was 323 (relative risk = 1.4; 95% confidence interval = 1.3 to 1.5). A significant association with basal cell carcinoma was found in four cancer types for men and in three for women. For skin malignancies other than malignant melanoma there was more than a sixfold increased risk for men (relative risk = 6.8; 95% confidence interval = 4.8 to 9.4) and more than a threefold increased risk for women (relative risk = 3.1; 95% confidence interval = 1.4 to 5.9) during the period after the diagnosis of basal cell carcinoma. During the period before the diagnosis of basal cell carcinoma, there were also increased risks (men: relative risk = 5.0; 95% confidence interval = 3.1 to 7.5; women: relative risk = 4.0; 95% confidence interval = 1.9 to 7.4). This was in contrast to the risks of malignant melanoma. Before the diagnosis of basal cell carcinoma there was no significant increased risk of malignant melanoma but after the diagnosis there was more than a sixfold increased risk for men (relative risk = 6.8; 95% confidence interval = 4.8 to 9.4) and more than a fourfold increased risk for women (relative risk = 4.2; 95% confidence interval = 1.5 to 9.2).(ABSTRACT TRUNCATED AT 250 WORDS)

We report on a patient with a pigmented basal cell carcinoma of the nipple. Despite its rarity, it is important to know about this tumour because it is so easy to confuse it with malignant melanoma.

We reviewed patient records of 99 consecutive orbital exenterations performed between 1969 and 1988. Patients ranged in age from 2 to 86 years (mean, 55.9 years). Classification of cases on histopathologic criteria showed 32 exenterations were performed for squamous cell carcinoma originating in the paranasal sinus (13), skin (12), conjunctiva (six), and lacrimal sac (one). Orbital exenteration was performed for treatment of other epithelial malignancy in basal cell carcinoma (eight), sebaceous carcinoma (six), adenoid cystic carcinoma (five), undifferentiated carcinoma (four), adenocarcinoma (two), intraepithelial carcinoma of the conjunctiva (two), benign mixed tumor (one), and transitional cell carcinoma (one). Exenterations were performed for melanoma of the conjunctiva (ten), nasosinus (three), skin (two), orbit (two), and choroid (one). Exenterations were also performed as treatment for mucormycosis (five), meningioma (three), fibrosarcoma (two), rhabdomyosarcoma (two), hemangiopericytoma (two), orbital cellulitis (one), fibrous histiocytoma (one), schwannoma (one), lymphangioma (one), benign lymphoepithelial lesion (one), and undifferentiated malignancy (one).

All the consultants agree that, given this patient's history, a common skin tumor like squamous cell or basal cell carcinoma is unlikely. Melanoma or Merkel cell carcinoma belong in the differential. Interestingly, the consultants all suggest a biopsy of the lesion prior to other testing, and because this tumor is so accessible, a biopsy should not interfere with further testing or treatment. Drs. Weymuller and Marks would then proceed with a CT scan; Dr. Ridge favors an MRI scan. While a chest-ray is in order to rule out metastases, Dr. Weymuller also suggests immunocytochemistry. All the experts agree that the primary tumor should be excised. Dr. Weymuller would perform a total parotidectomy with facial nerve preservation, while Drs. Marks and Ridge suggest a superficial parotidectomy with facial nerve preservation. Drs. Weymuller and Ridge would also perform a modified radical neck dissection. In the absence of cervical disease, Dr. Marks would treat the neck primarily with radiotherapy. Only Dr. Weymuller favors immediate reconstruction and would use a lower trapezius island flap or a large rotational flap. Drs. Marks and Ridge prefer primary closure or skin graft. Drs. Weymuller and Ridge would treat this patient with combined therapy, giving radiotherapy to the primary area and the neck postoperatively at a dose of 55-60 Gy. However, Dr. Marks would treat the primary site postoperatively and the neck primarily with radiotherapy. He would treat the primary site with 59.40 Gy and the neck with 50.40 Gy.(ABSTRACT TRUNCATED AT 250 WORDS)

Non-melanoma skin cancer (NMSC) differs from other forms of cancer by a high incidence combined with a very low lethality. In Denmark there is a well-established registration system of both the cause of death and the incidence of cancer. In 1984, 2,984 cases of NMSC were notified to the Cancer Register while, according to the Register of Causes of Death, 40 persons were registered as having died from NMSC. These 40 cases were investigated further by means of information from the case records and the general practitioners. In only 18 out of the 40 cases death was caused by NMSC, basal cell carcinoma with invasion into vital organs in three cases and metastasing spinocellular carcinoma in 15 cases. Over half of the fatal cases of spinocellular carcinoma were localized around the outer openings on the face, primarily (n = 4) around the external auditory meatus. In this review, the estimated lethality for basal cell carcinoma was 0.12% and for spinocellular carcinoma 4.3% the latter being high compared with other studies. Comparable population based studies are not available due to less effective registration systems.

Chlorofluorocarbon-11 (CFC11) lasts for an average of 74 years in the atmosphere, CFC12 for an average of 111 years, and CFC113 for an average of 90 years. Every CFC molecule destroys thousands of molecules of stratospheric ozone. Recently, the extent of the Antarctic ozone hole has been recognized. The depletion of stratospheric ozone may lead to increase ultraviolet-B (UV-B) radiation. UV-B radiation has many damaging effects on human health, such as snow blindness, cataract and skin cancer. UV-B radiation also suppresses the immune defenses against certain infections. While it is difficult to estimate the numerical effect on the basis of epidemiologic data in the U.S. A., UNEP and WHO estimate that for every 1% decrease in stratospheric ozone, there will be between a 0.3 to 0.6% increase in cataract. They also estimate that for every 1% depletion of ozone, the incidences of basal cell carcinoma, squamous cell carcinoma and malignant melanoma will increase 2.7, 4.6 and 0.6%, respectively. There is also concern that increased UV-B radiation might lead to an increase of the incidence and severity of infectious diseases due to suppression of the immune system. Since the data on UV-B exposure are extremely limited, it is necessary to confirm the incidence rate of skin cancer in various countries in relation to UV-B exposure.

This paper gives a short review on the function, pharmacokinetics, and therapeutic application of recombinant interferon-gamma (rIFN-gamma) in dermatology. Simultaneously, our own experiences are presented for 57 patients (phase II study) suffering from genital warts (21 patients), psoriatic arthritis (10 patients), psoriasis vulgaris (three patients), malignant melanoma (six patients), bowenoid papulosis (four patients), Behcet's disease (four patients), basal cell carcinoma (six patients), as well as herpes simplex recidivans, epidermodysplasia verruciformis, and mycosis fungoides (one patient each). We conclude that there might be an indication for treatment with rIFN-gamma in genital warts, bowenoid papulosis, Behcet's disease, and microbial infections, such as leprosy and cutaneous leishmaniasis. Even though there are reports of a limited beneficial effect of rIFN-gamma on arthritis and skin lesions in psoriasis, we failed to observe any in 10 patients. The main side effects in our low-dose study (50-100 micrograms/d) were mild fever (78%), fatigue (78%), and myalgia (65%). Laboratory tests revealed an increase in the serum triglyceride level, in particular, in psoriatic patients.
