[Liposarcoma of the thumb].

Liposarcoma is the most common malignant deep soft-tissue tumor in adults. however, primitive cutaneous liposarcoma is very rare. We report the observation of a patient who presents a liposarcoma of the thumb.

[Skin and menopause].

Important changes related to declining level of several hormones occur during menopause: vasomotor instability, bone loss, anxiety, sexual dysfunction, skin aging... Our objective was a review of the literature concerning the histological and clinical changes seen in post menopausal skin, and also an analysis of the effect of hormonal replacement therapy in slowing down the aging process. Decline in progesterone increases the impact of androgen on the sebaceous glands and hair. Decreased estrogen slows down mitotic activity in the epidermal basal layer, reduces the synthesis of collagen and contributes to thickening of the dermo-epidermal junction. This hypoestrogenemia may be spontaneously attenuated by local synthesis of oestradiol in peripheral target tissues according to the intracrine process. This new hormonal pattern is associated with skin atrophy, hyperseborrhea, increased pilosity on the cheeks and upper lip, loss of scalp hair, increase in degeneration of elastic tissue, atrophy and dryness of the vaginal mucosa. Estrogen treatment in post menopausal women has been shown to increase collagen content, dermal thickness and elasticity. Biophysical properties are also significantly improved for the parameters reflecting hydration and sebum secretion. However, numerous side effects such as increased incidence of cancer and cardiovascular morbidity limit the use of this treatment. So non hormonal alternatives are proposed. Laser and lifting remain the most important options.

[Pseudoainhum and peripheral neuropathy].

BACKGROUND: Pseudoainhum is a rare disease characterised by gradual fibrous constriction of the fingers and/or toes eventually resulting in their amputation. In this article, we report the first case seen in Morocco, highly unusual in terms of its severity. CASE REPORT: A 46-year-old woman with no toxic habits was hospitalised for spontaneous amputation of the fingers and toes. This condition began when the patient was 12 years old with the appearance of a circular constriction band at the base of the fifth toe, eventually resulting in its loss. The patient gradually lost all her other toes and fingers except for the first joint of her left index finger. There was no family history of any similar condition. Clinical examination also revealed perforating plantar disease in two of the stumps and peripheral neuropathy in all four limbs, comprising predominantly axonal disease responsive to electromyogram. Amputation of the index finger was completed and histological examination of the removed section showed nothing unusual, with no signs of diabetes. DISCUSSION: The peculiarity of our case resides in the exceptional severity of these amputations and their association with isolated polyneuropathy. Pseudoainhum has been described chiefly in patients with congenital keratoderma, certain systemic diseases, diabetes and alcohol dependence. A number of etiopathogenic hypotheses have been suggested: traumatic, infectious, vascular, neurological and genetic processes.

[Porphyria cutanea tarda in a hemodialysed patient with hepatitis C virus infection: efficacy treatment by small repeated phlebotomies].

INTRODUCTION: Porphyria cutanea tarda (PCT) is a disorder of heme biosynthesis resulting from deficiency in the enzyme uroporphyrinogen decarboxylase. In the sporadic form of PCT, there are many agents that trigger the clinical manifestations. EXEGESIS: We report a case of PCT in an hemodialysed patient with hepatitis C virus infection (HVC). He was treated with small repeated phlebotomies of 50 ml every week with photoprotection, eviction of traumatismes and inducing drugs. A clinical remission was induced after five months of treatment. CONCLUSION: A proper diagnosis of PCT in non uremic hemodialysed patients requires fractionation of serum and fecal porphyrin changes. Management of this patients is difficult. Small repeated phlebotomies (50-100 ml) could be an interesting therapy.

[Idiopathic hypereosinophilic syndrome and bullous pemphigoid].

BACKGROUND: We report the case of bullous pemphigoid associated with hypereosinophilic syndrome. This association has only been report only once in the literature. CASE REPORT: A 58 year-old man was admitted for a surinfected, pruriginous and generalized bullous dermatosis. Physical examination revealed bronchial rales. The cutaneous histology showed a junctional and intradermic cleavage associated with massive dermal infiltration by eosinophils. The diagnosis of a pemphigoid was confirmed by immunology. In parallel, the idiopathic hypereosinophilic syndrome was evoked in view of persisting hypereosinophilia without detected aetiology and associated with pulmonary infiltration. The skin lesions disappeared under symptomatic treatment, but the patient was rehospitalized 4 months later for severe relapse of dermatosis associated with medullary infiltration by eosinophils. Oral corticosteroid therapy gave spectacular results on both skin and blood formula. DISCUSSION: This association is rare, but seems to be related by the same immunological factors highlighting eosinophils. In addition, the presence of hypereosinophilic syndrome gives the pemphigoid some particular clinical, histological and evolutive characteristics.

[Maffucci syndrome associated with epidermoid carcinoma of the nasopharynx].

BACKGROUND: Maffucci's syndrome is a dysembryoplasia of the mesoderm, explaining the dual involvement of cartilage and vascular tissue. The risk of malignant degeneration or associated tumors is high in this uncommon disease. We report a case of Maffucci's syndrome associated with squamous cell carcinoma of the cavum. CASE REPORT: A 37-year-old man consulted for multiple angiomas and chondromas which had developed since childhood. The diagnosis of Maffucci's syndrome was obvious. Radiological exploration of the limbs confirmed chondromatosis and biopsy of the cavum performed because of the occurrence of epistaxis, revealed squamous cell carcinoma. DISCUSSION: Maffucci's angiochondromatosis is a rare, non-hereditary but sometimes congenital disease. Angiomas predominate on the hands and feet. Sarcomatous degeneration is the main complication of these chondromas. Angiomas rarely become malignant, but when they do are generally more aggressive than chondromas. The frequency of neoplasia in Maffucci's syndrome would suggest that there is a supplementary oncogenic factor. Several types of malignancy associated with Maffucci's syndrome have been reported, but to our knowledge there has been no publication concerning an association between Maffucci's syndrome and squamous cell carcinoma of the cavum.
