[Pseudoxanthoma elasticum-like disease with deficiency of vitamin K-dependent clotting factors and cutis laxa features].

Background: Pseudoxanthoma elasticum (PXE)-like syndrome is characterized by the association of PXE and cutis laxa (CL) features with a deficiency of vitamin K-dependent clotting factors. It was first described in 1971 and was identified as a distinct genetic entity in 2007 with analysis of the GGCX (γ-glutamyl carboxylase) gene, which is involved in congenital deficiency in vitamin K-dependent clotting factors. Here we report a new case of this extremely rare syndrome.

[Lymphocytic infiltrate of the dermis preceding typical Sweet's syndrome].

Background: The histologic criteria for Sweet's syndrome consist in prominent oedema of the dermis and a diffuse infiltrate of numerous neutrophils with leukocytoclasis without vasculitis in the superficial and the deep dermis. Several comorbidities have been observed in patients with Sweet's syndrome, particularly hemo-proliferative diseases.

Patients: We report the cases of two men aged 60 and 75 years with Sweet's syndrome associated in one case with myelodysplasia and in the other with chronic lymphocytic leukemia.

[Leukocytoclastic vasculitis with severe renal involvement following Parvovirus B19 primary infection].

Background: Leukocytoclastic vasculitis following Parvovirus B19 primary infection has occasionally been reported in children but it occurs rarely in adults. We present an original case report with severe renal complications.

Patients And Methods: A 33-year-old man presented with fever and eruption of the abdomen and members.

[Multiple abscesses induced by self injection of zolpidem].

Background: Zolpidem, a hypnotic drug, is occasionally taken in high doses by some drug addicts for its hallucinogenic properties.

Case Report: We report the original observation of a young female addict who developed aseptic cutaneous abscesses on the forearms and feet induced by self injection of powdered zolpidem. Histopathological analysis revealed birefringent vegetal structures.

[Actinomycosis of the buttock].

Introduction: Cutaneous actinomycosis of the buttocks is a rare granulomatous bacterial infection that usually starts in the perianal area. We present an exceptional case in the form of a pseudo-tumor.

Case Report: A 69 year-old woman, in general good health, developed an indurate mass on the supra-external quadrant of the right buttock.
