[Subacute cutaneous lupus erythematosus in childhood: a case report].

Subacute cutaneous lupus erythematosus is extremely rare in childhood. We report the case of a 7 year-old girl who presented annular erythematous infiltrated lesions on sun exposed areas since the age of 2 months. Histopathologic examination showed orthohyperkeratosis, epidermal atrophy, widespread hydropic degeneration of epidermal basal cell layer, and a dermal lymphohistiocytic infiltrate. The lupus band test was negative. The immunological investigations (antinuclear antibodies) were negative. Treatment with antimalarials, topical steroids and sun protection allowed clearance of the cutaneous lesions. Lesions relapsed after antimalarials discontinuation and sun exposure. Four years later, at the age of 11, the antinuclear antibodies became positive. The diagnosis of subacute cutaneous lupus erythematosus is based on the clinical aspect of lesions, topography, histological finding, evolution and immunological profile of the patient.

[Adverse effects of intralesional Glucantime in the treatment of cutaneous leishmaniosis].

OBJECTIVE: The treatment of cutaneous leishmaniasis used in Tunisia is Glucantime. The aim of this retrospective study was to determine the adverse effects of intralesional Glucantime and to calculate the risk/benefit rate of this treatment. RESULTS: Adverse effects were observed in 14 cases (5%). For facial lesions, we observed facial staphylococci in 2 cases, stibio-intolerance in 1 case, and a palpebral subcutaneous nodule in 1 case. In limb lesions the complications were: sporotrichoid nodules in 5 cases, vagal malaise (1 case), pyodermitis (1 case), erysipelas (1 case), necrosis (1 case), and urticaria (1 case). COMMENTARY: The adverse effects of intralesional Glucantime are mostly infections, mainly observed in cephalic localization, and stibio-intolerance. For this reason, intralesional injection of Glucantime must be avoided in the cephalic region.

[Cowden's disease: a new paediatric observation].

We report on a paediatric observation of Cowden's disease in a 6-year-old child. Familial steroid-resistant nephrotic syndrome was associated to papulous and papillomatous lesions of gingiva and oral mucosa, multiple hamartoma of the back and of upper limbs, facial dysmorphism and follicular thyroid cancer. Thyroid cancer evolved favorably after surgical treatment, radioactive iodine and L-thyroxin supplementation. Nephrotic syndrome evolved to chronic renal insufficiency after 11 years. The early diagnosis of Cowden's disease, or multiple hamartoma syndrome, allows a careful monitoring of the patients who are facing the risk of cancer transformation, which is the principal complication of the condition.

[Gingival metastasis in breast phyllodes tumor].

BACKGROUND: The metastasis of oral cavity is rare. We report a gingival metastasis in the course of low grade phyllode sarcoma of the breast which is usually little metastatic. CASE-REPORT: A 44 year old woman was operated two years ago for a phyllod sarcoma of the breast histologically confirmed. She presented for a mandibular exophytic tumour associated with haemorrhagic, necrotic, ulcerated and bulking gingivitis surrounding at the level of the maxillary and mandibular gingiva. The examination revealed multiple nodular lesions of the trunk and the scalp. The histological examination confirmed the diagnosis of cutaneous and gingival metastasis of the phyllod sarcoma of the breast. The evolution was rapidly fatal. DISCUSSION: The gingival metastasis are rare tumours with a bad prognostic. Their diagnosis is based on clinical and histological arguments and must be made different from chronic gingivitis which can be associated.

[Biermer disease disclosed by mucous ulcerations].

Pernicious anemia rarely induces mucous membranes lesions, wich, exceptionally reveal the disease. We report a case of a 64-year-old man who presented a clinical history of recurrent painful ulcerations of the buccal, genital and ocular muosa. He also had peripheral sensory nerve impairement of the legs. The diagnosis of pernicious anemia was made after a 19 year course. Cobalamin supplementation induced an improvement of the mucous membrane lesions and of the anemia, but recurence occurred each time the treatment was stopped. Our observation is particular by the multiple mucous membrane involvement revealing pernicious anemia and by the ocular lesions which had never been previously reported.

[Profile of basal cell carcinomas of the scalp after radiotherapy for tinea capitis (about 63 cases)].

The induction of basal cell carcinoma (BCC) of the scalp by X-ray therapy for tinea capitis is well known. The aim of the study was to specify the epidemiological, clinical and histological characteristics of this disease. In a retrospective study, we collected data from the files of 63 patients, with a history of radiotherapy for tinea capitis, followed between January 1995 and December 2004. Fifty one men and 12 women with a total of 108 BCC of the scalp are reported (1.76 lesion per patient and 1.13 cm on average of diameter). The mean age at the occurrence of the BCC was 45.5 years. Thirty seven percent of BCC occurred on the occipital area; 28.7% were in the parietal site. The most frequent clinical aspect was the nodular BCC (51%) and the cicatricial BCC (35%). Histological study showed a nodular aspect in 74 % and pigmentation in 62% of cases. It is concluded that BCC of the scalp following X-ray therapy for tinea capitis have some clinical and histological particularities. It represents the most frequent tumour developing on irradiated scalp.

Erysipelas after breast cancer treatment (26 cases).

Erysipelas is a bacterial hypodermal cellulitis usually associated with Streptococcal infection. Erysipelas of the upper limbs in women treated for breast cancer is relatively rare. We undertook a 10-year retrospective study identifying 26 cases of erysipelas of the upper limb following treatment for breast cancer; we describe the clinical, therapeutic, and evolutionary aspects. The age of our patients ranged from 37 to 80 years with a mean age of 53. All patients had a breast surgery and lymphadenectomy. Fifteen patients had chemotherapy and 23 had radiotherapy. The erysipelas appeared with an average of 5.23 years after cancer treatment (3 months to 15 years) and was recurrent in nine cases. Lymphedema occurred in eighteen patients. The first signs were fever and shivering in 25 patients. The clinical aspect was an inflammatory plaque. The physical findings of erysipelas included a raised edge (6 cases), blisters (1 case), purpura (1 case), and cellulitis (1 case). The portal of entry was not found in eleven patients. The upper limb was affected in all cases. Involvement of the axillary folds or the chest was observed in eight cases. Treatment with penicillin was undertaken for all patients; the length of treatment varied from 11 to 26 days. Lympadenectomy and radiotherapy in breast cancer may lead to lymphedema, which can be evident or sometimes discrete. Those patients who developed erysipelas in our series usually fared well with treatment, but many had recurrences attributed to persistent lymphedema. It was also of note that for many patients in this series, the portal of entry was not identified.

[Radiotherapy-induced pemphigus: a case report].

A 61-year-old male patient suffering from squamous cell carcinoma of the lower lip developed pemphigus vulgaris two months after exposure to radiotherapy. Skin lesions were initially localised to the face and neck and later extended over other skin areas. The eruption are improved with glucosteroid therapy, which were stopped after six months. Pemphigus induced by radiotherapy is rare, latency before the onset of the vesiculobullous eruption is variable. Clinical, histological and immunological characteristics are similar to those of other types of pemphigus.

[Glucantime injection: benefit versus toxicity].

UNLABELLED: Glucantime is the most common stibied derivative used to treat cutaneous leishmaniasis (CL) in Tunisia; however adverse effects have been reported. OBJECTIVES: This retrospective study deals with the various adverse of intramuscular glucantime used for CL. RESULTS: Nineteen patients (21%) receiving intramuscular Glucantime developed adverse effects. 8 male and 11 female patients, mean age 45, ranging from 8 to 84 years were affected. adverse effects were: fever (3), arthralgia and myalgia (4), nausea and vomiting (2), erythema nodosum (1), acute renal failure (3 including 1 lethal case), hepatic cytolysis (1), skin rash (4), and inflammation of the injection site (1). CONCLUSION: Adverse effects of intramuscular Glucantime were relatively frequent in our series. Arthralgia, myalgia, and skin rash were not severe and disappeared when the treatment was stopped. Stibiointoxication cases, mainly acute renal failure, were serious.

Identification of Malassezia species from Tunisian patients with pityriasis versicolor and normal subjects.

BACKGROUND: The genus Malassezia (Pityrosporum), recognized as a member of microbiological flora of the skin in humans and warm-blooded animals, has been recently revised to include 10 Malassezia species. The aim of the study was the isolation, identification and analysis of Malassezia species distribution in skin of healthy volunteers and lesions of pityriasis versicolor (PV). MATERIAL AND METHODS: Specimens were taken from 100 patients with PV and 30 healthy volunteers. Cultures were made in modified Dixon agar medium and the isolates were identified by morphological and physiological methods: macroscopy, microscopy, catalase, beta-glucosidase and lipid assimilation tests. RESULTS: Malassezia globosa was the predominant species in lesional skin of PV (65%). It was isolated alone in 47% of cases and associated in 18% with M. furfur (13%) or M. sympodialis (5%). In healthy skin M. globosa was found alone in 7.77% and associated in 15.54%, respectively, with M. furfur (4.44%), M. sympodialis (4.44%), M. restricta (3.33%) and M. slooffiae (1.11%). CONCLUSION: From these findings it was suggested that M. globosa presents the main species implicated in the pathogenicity of PV and M. furfur as the second agent of importance.

[Bleomycin induced flagellate erythema].

Bleomycin is an antibiotic with antineoplastic pro prieties. It is used in the traitement of many syndromes. The cutaneous toxicity of bleomycin includes many alteration. We report a case of flagellate erythema following the administration of bleomycin in a 57-year-old women with Kaposi sarcoma. She developped linear lesions 6 days after the first dose of bleomycin. Flagellate erythema is a specific reaction to bleomycin therapy wich occurs in susceptible individuals independently of dose, route of administration and type of malignant disease treated. Its occurs in 10 to 35% of the treated patients.

[The cutaneous leishmaniasis of the face in Gafsa area, Tunisia].

The cutaneous leishmaniasis is a frequent affection in Tunisia. In the Gafsa region it is a endemoepidemic infection. Our prospective study was carried out on 225 cases of cutaneous leishmaniasis of the face collected over two years in the outpatients' department of dermatology at Gafsa hospital. The aim of our study was to know more about the evolutive epidemio-clinical particularities of the cutaneous leishmaniasis of the face. The relative frequency of the cutaneous leishmaniasis of the face for the new patients reached 5%. An equal distribution between the two sexes was noted. The average age of our patients was 24 years old and 6 months old with extremes ranging from 3 months to 77 years. The nodular and ulcerated forms were the most frequent (35.3%), followed by impetiginoid forms (23%), then the lupoid forms (15%). The papular form was quite frequent (13%). Impetiginoid lesions occurred frequently in the child. Lupoid lesions appeared particularly on the nose. The complicated forms: the cutaneuos necrosis or erysipelas of the face appeared after intralesional injections of meglumine antimoniate (Glucantime). The intramuscular meglumine antimoniate was used in 172 patients, among them 47 needed two treatments or more because of a particular resistance of the lesions of the face. The pimple of Gafsa, term initially used for ulcerated skin nodules, was actually characterised by a lesional polymorphism. The prognosis was good however the risk of in aesthetic scar of the face was important.
