The term fasciitis-panniculitis syndrome (FPS) is proposed as a novel compilation encompassing several disorders, common to which is subcutaneous induration caused by cicatrizing fasciitis as well as septal and lobular panniculitis and perimysial fibrosis. Included herein are Shulman's eosinophilic fasciitis, morphea profunda, lupus profundus, venous lipodermatosclerosis, toxic oil syndrome, altered tryptophane-related eosinophilic myositis, graft-versus-host reaction, and fasciitis reactive to subjacent basal cell carcinoma. FPS should be differentiated from scleroderma, which primarily affects the dermal structures and in which arterioles are injured. In contrast, vasculopathy of the subcutaneous medium-sized veins accompanies the hypodermal lesions of FPS. The importance of recognizing and grouping these disorders lies in their different histopathology, characterization as reactive phenomena, enhanced responsiveness to treatment, and better prognosis than scleroderma. In view of the excellent prognosis of FPS, steroid treatment is not warranted. Long-term therapy with cimetidine appears to benefit the majority of patients.

Skin affected by a burn cancer is scarred, ulcerated, and often appears as erythema ab igne clinically in adjacent skin. The latent period in burn scar malignancy is much longer for SCC than BCC. Malignant melanoma and various sarcomas are reported to arise in burn scars, too. The other extreme on the temperature scale can less often result in enough permanent acral damage that poor wound healing may eventually result in cancer, usually SCC. About 1% of patients with chronic osteomyelitis develop cancer, usually SCC in sinus tracts. As with tumors arising in burn scars and chronic leg ulcers of varied etiology, black patients are disproportionately overrepresented in osteomyelitic malignancy. In nearly all of the patients with radiation-induced skin cancer, concomitant radiodermatitis is present. As with burn scar and osteomyelitic cancer, x-ray related cancer has a long latent period. Similar to burn scar cancer, SCC predominates in osteomyelitis and occurs on the extremities. BCC, when it arises, is more common on the face and neck in burn- and radiation-induced tumors. Multiple tumors are frequent as is recurrence in x-ray malignancy. Mortality is high: one out of three to four patients with burn scar, osteomyelitic, and radiation cancer die of dermatosis-related malignancy. Recently, radioactivity-contaminated gold rings have been implicated in causing SCC. Carcinoma tends to occur in irradiated benign dermatoses whereas sarcomas tend to complicate irradiated malignancies. Stasis ulceration and anogenital fistulae may rarely lead to cancer, SCC in the former and adenocarcinoma in the latter. SCC can rarely develop in four related conditions (acne conglobata, dissecting perifolliculitis of the scalp, hidradenitis suppurativa, and pilonidal sinus) after a lengthy latent period; prognosis is poor with a high metastatic rate. A whole host of chronic cutaneous infections can lead to malignancy occasionally; these include lupus vulgaris, lymphogranuloma veverum, granuloma inguinale, leprosy, actinomycosis, and candidiasis. BCC more than SCC is known to complicate smallpox vaccination sites. Certain erosive and/or scarring dermatoses other than those mentioned above can be unusually affected by secondary malignancy. Discoid lupus erythematosus lesions often subjected to the carcinogenic effects of sunlight can degenerate into SCC in patients with either light or dark skin. In acrodermatis chronica atrophicans, a condition not often seen in the United States, the involved skin, particularly of the lower extremities, is susceptible to SCC, lymphoma, and BCC. Epidermolysis bullosa, especially the recessive dystrophic variant, can be complicated by SCC on affected mucous membrane and acral skin.(ABSTRACT TRUNCATED AT 400 WORDS)

Dermal tattooing has been performed for over 4,000 years. Some of the reported complications from tattooing include pyogenic infections, viral hepatitis, syphilis, tuberculosis cutis, rubella, herpes simplex, herpes zoster, psoriasis, lichen planus, lupus, pigment allergy and sensitivity, keloids, sarcoidal granulomas, erythema multiforme, malignant melanoma, squamous cell carcinoma, and basal cell carcinoma. Most complications can be avoided by utilizing proper aseptic technique and avoiding exotic pigments. A survey of the members of the American Society of Ophthalmic Plastic and Reconstructive Surgery was taken to determine the prevalence of eyelid tattooing and complications encountered. The findings of this survey are presented.

Following skin damage resulting from radiotherapy, pancancerous conditions, carcinomas and basal cell carcinomas not rarely pose therapeutic problems. We encountered those problems severally after radiotherapy of the middle face, for instance for lupus vulgaris or basal cell carcinoma. Senile skin changed over the years by climatological influences may create similar problems. Disorders of blood supply and lack of "tissue material" as consequences of radiation-induced skin atrophy are the reasons for the failure of many attempts of plastic surgery aimed at tumor removal and defect repair. Besides that, the conditions for such operative procedures are progressively deteriorating with the number of tumor recurrences. In these instances cryotherapy offers an excellent therapeutic alternative by virtue of the favorable healing tendency of the cryonecrosis including the final, inconspicuous scar formation.

We describe a patient with systemic lupus erythematosus (SLE) and antiphospholipid antibody syndrome (APLS) who developed a plaque-like lesion around the mouth and lost all body hair. Biopsies of the circumoral lesion and scalp, were originally reported as containing extensive basal cell carcinoma, but on review, both showed the typical appearance of a benign malformation of the hair follicle known as basaloid follicular hamartoma. Regrowth of hair and partial resolution of the peri-oral plaque occurred with more aggressive treatment of her SLE, but the basaloid follicular hamartomas in her scalp skin persisted. There is a known, but rare, association between this pattern of basaloid follicular hamartoma, alopecia and myasthenia gravis, but only two cases have been described in association with SLE and none with APLS.

The TUNEL (terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling) technique has been described as sensitive method of labeling apoptotic nuclei in tissues, which preferentially stains apoptotic strand breaks. In the current study, three commercially available TUNEL kits for paraffin-embedded and cryostat tissues were tested to optimize this method for the studies on human skin. The investigation included normal skin (n = 10), atopic eczema (n = 4), basal cell carcinoma (n = 5), and lupus erythematosus (LE) (n = 31) sections. Additionally, the expression of certain apoptotic markers (Fas antigen and Bcl-2 protein) was studied immunohistologically on normal and LE skin. During TUNEL labeling according to the manufacturers' protocols, abnormally high background and nonspecific staining were found in all skin sections. The manipulation with the pretreatment time and, in particular, the introduction of an additional step (terminating the labeling reaction by inhibiting the terminal deoxynucleotidyl transferase activity) in two kits led to a remarkable improvement in their performance. The conclusions are that it is generally difficult to establish a functionally specific TUNEL technique for skin sections and that the choice of a kit is absolutely crucial for obtaining reliable results. Considering the extent to which the apoptosis research has been carried out recently, it is advisable to remain critical in evaluating the results. Further, it is necessary to combine the TUNEL technique with the investigation of other apoptotic markers.

Lupus vulgaris (LV) is the most common morphological variant of cutaneous tuberculosis. However, the occurrence of bizarre clinical presentations over atypical sites often leads to misdiagnosis and inappropriate treatment causing significant morbidity. This report seeks to highlight two unusual cases of lupus vulgaris occurring on the face of immunocompetent women and remarkably mimicking periorbital cellulitis and basal cell carcinoma, respectively. The diagnosis was confirmed by histopathology, an enzyme-linked immunosorbent assay (ELISA) test for Mycobacterium tuberculosis and polymerase chain reaction (PCR). With four-drug antitubercular therapy, both patients had a dramatic response.

Systemic isotretinoin has been used to treat severe acne vulgaris for 20 years. However, isotretinoin also represents a potentially useful choice of drugs in many dermatologic diseases other than acne vulgaris. Diseases such as psoriasis, pityriasis rubra pilaris, condylomata acuminata, skin cancers, rosacea, hidradenitis suppurativa, granuloma annulare, lupus erythematosus and lichen planus have been shown to respond to the immunomodulatory, anti-inflammatory and antitumor activities of the drug. Isotretinoin also helps prevent skin cancers such as basal cell carcinoma or squamous cell carcinoma. A combination of systemic isotretinoin and interferon-alpha-2a may provide a more potent effect than isotretinoin alone in the prevention and treatment of skin cancers.Systemic isotretinoin may be considered as an alternative drug in some dermatologic diseases unresponsive to conventional treatment modalities. However, randomized clinical trials aimed at determining the role of systemic isotretinoin therapy in dermatologic diseases other than acne vulgaris are required.

Cathepsin (Cat) L is an important lysosomal proteinase involved in a variety of cellular functions including intracellular protein turnover, epidermal homeostasis and hair development. Hurpin (serpinB13) is a cross-class specific serine protease inhibitor of Cat L. We have analysed the expression and localization of Cat L and hurpin in various inflammatory and neoplastic diseases by immunohistochemistry. Whereas Cat L expression in normal skin was below detection limit, immunoreactivity was detected in chronic inflammatory dermatoses. The highest expression of Cat L was found in psoriasis, atopic eczema and squamous cell carcinoma (SCC) samples. Samples of Lupus erythematosus, folliculitis, acne inversa, chronic leg ulcers and pyoderma gangrenosum demonstrated similar but lower expression for Cat L. In malignant cells of SCC, basal cell carcinoma and malignant melanoma, characteristic staining patterns were observed for Cat L, with more abundant expression at the periphery of the tumor. Expanding our previous work, we found that the expression of hurpin was confined mainly to the basal layer in normal skin samples, whereas hurpin was overexpressed and redistributed in diseased skin. The localization of hurpin in dermatoses and neoplasias differed from that in normal skin in that the highest expression was found in the outermost layers of the granular and upper spinous layers. Similarly to Cat L, the highest expression for hurpin was found in psoriasis and SCC. The results presented here summarize for the first time the expression of the protease Cat L and its inhibitor hurpin in a broad spectrum of skin diseases.

Cutaneous sporotrichosis, a subcutaneous mycotic infection is caused by the saprophytic, dimorphic fungus Sporothrix schenckii. It commonly presents as lymphocutaneous or fixed cutaneous lesions involving the upper extremities with facial lesions being seen more often in children. The lesions are polymorphic. The therapeutic response to saturated solution of potassium iodide is almost diagnostic. We describe a culture-proven case of cutaneous sporotrichosis of the face mimicking lupus vulgaris initially and basal cell carcinoma later, who did not tolerate potassium iodide and failed to respond to treatment with fluconazole. The patient had reactivation of infection following an infiltration of the scar with triamcinolone acetonide injection. Various other aspects of these unusual phenomena are also discussed.
