The dilemma of treating pyoderma gangrenosum associated with monoclonal gammopathy of undetermined significance.

Pyoderma gangrenosum (PG) is a rare ulcerative skin condition. It can be associated with a number of systemic diseases. Association with monoclonal gammopathy of undetermined significance (MGUS) is uncommon, but prognosis may be different depending upon the type of MGUS. Cases of MGUS- related PG reported in the literature with data concerning evolution and treatment were identified through a PubMed search. A patient with recurrent PG in the setting of a MGUS-IgA-? in our department was also included. In total, 10 cases were identified. Only the two cases with Ig populations other than IgA improved without recurrence after treatment of the PG. All the patients with MGUS-IgA showed recurrences. Early multiple myeloma was proposed for three patients with MGUS-IgA-related PG. Second or third line treatments were necessary in some cases.

The association between bullous pemphigoid and comorbidities: a case-control study in Moroccan patients.

BACKGROUND: Comorbidities of bullous pemphigoid (BP) have not been thoroughly described in Morocco. This study investigates clinical features, comorbidities, and medications in a cohort of Moroccan patients with confirmed BP to help decrease morbidity and mortality. MATERIAL AND METHODS: This cross-sectional study involved 81 cases of BP diagnosed in 2015-2018 and 162 age- and sex-matched controls with complete follow-up at the Department of Dermatology in a university hospital setting. RESULTS: Eighty-one individuals were included in the study; the mean age at diagnosis was 71.3 years, and 53% were men. The most common comorbidities were hypertension (58%), type 2 diabetes (43%), and dyslipidemia (31%). Almost a quarter of the cohort (28%) had been diagnosed with at least one neurological disease before the onset of BP. BP was significantly associated with the presence of malignancies (14%; p = 0.017) and stroke (16%; p = 0.009) compared to an age-matched control group. The most common standard medications were beta-blockers, diuretics, and statins. In total, 86% of the patients with type 2 diabetes were taking antidiabetic drugs, especially metformin (82%) and gliptins (51%). CONCLUSION: This study showed that BP is associated with stroke and the presence of malignancy compared to the age-matched general population. This study also calls for investigation into the specific role of some drugs as inducing factors for BP.

[Vitiligo revealing Vogt -Koyanagi-Harada disease]. / Vitiligo révélant une maladie de Vogt-Koyanagi-Harada.

Vitiligo is a chronic auto-immune skin disease, often associated or discovers other autoimmune pathologies. His association with Ophthalmological type pan uveitis and/or neurological type of meningitis and/or inner ear type of hearing loss determines the disease or Vogt -Koyanagi-Harada syndrome (VKH). We related the case of a young woman who consulted for recurrent uveitis for a year, and it was only with the onset of vitiligo lesions that VKH disease diagnosis was discussed and confirmed.

[Soft tissue melanoma: a clinical case]. / Mélanome des tissus mous: cas clinique.

Soft tissue melanoma was first described by Enzinger in 1965 under the name of clear cell sarcoma. In 1983, Chung and Enzinger renamed it soft tissue melanoma due to its immunohistochemical similarities with melanoma. We here report the case of a 22-year old young man with this rare type of melanoma, presenting with molluscoid lesion on his ankle without any clinical sign of malignancy. Histology examination confirmed the diagnosis of soft tissue melanoma.

[Pseudo-condylomatous neurodermatitis of the anal margin]. / Forme pseudo-condylomateuse d'une nevrodermite de la marge anale.

Cerebral venous thrombosis (CVT) is a rare origin of stroke, the clinical presentation and etiologies vary. The prognosis is shown to be better compared to arterial thrombosis. Magnetic Resonance Imaging (MRI) and MR Venograpgy (MRV) are currently important tools for the diagnostic. We studied 30 cases of CVT diagnosed in the department of neurology of the University Hospital of Fez (Morocco). Patients diagnosed with CVT signs between January 2003 and October 2007 were included in the study. Cerebral CT-scan was performed in 27 cases (90%) while the MRI examination was done in 18 patients (67%); and most patients (90%) received anticoagulant therapy. The mean age of our patients was of 29 years (age range between 18 days and 65 years). A female predominance was observed (70%). The clinical presentation of patients was dominated by: headache in 24 cases (80%), motor and sensory disability in 15 cases (50%), seizures in 10 cases (33%) , consciousness disorder in 10 cases (33%). CVT was associated to post-partum in 10 cases (33%), infectious origin in 8 cases (26%), Behcet disease in 2 cases (7%), pulmonary carcinoma in 1 case, thrombocytemia in 1 case and idiopathic in 7 cases (23%). The evolution was good in 20 cases (67%), minor squelaes were observed in 6 patients (20%), while major squelaes was observed in 2 cases. Two cases of death were registered. The CVT is a pathology of good prognosis once the diagnosis is promptly established and early heparin treatment initiated.
