Pityriasis lichenoides et varioliformis acuta (PLEVA) presents with haemorrhagic papules that resolve to leave varioliform scars. It is usually a self-limiting acute dermatosis. It is also known as Mucha Habermann disease. Histology of PLEVA Pityriasis lichenoides et varioliformis acuta (PLEVA) PLEVA is characterised by red patches that quickly evolve into papules 5-15 mm in diameter. They are often covered with a fine mica-like adherent scale. The centre of the papules often becomes filled with pus and blood or eroded with the overlying red-brown crust Page views in 2021 to date (this page and chapter topics): 242,45 Pityriasis lichenoides has an acute and chronic phase. The acute form is called Pityriasis lichenoides et varioliformis acuta (PLEVA) or Mucha-Habermann disease. The chronic form is usually designated as pityriasis licehnoides chronica. These two diseases from a spectrum of a self-limited dermatosis with the acute form starting as a maculopapular, erythematous eruption which heals to form superficial variable scars Page views in 2021 to date (this page and chapter topics): 785,64

You may see some epidermal cell necrosis as well Febrile ulceronecrotic Mucha-Habermann disease (FUMHD) is a rare and severe form of pityriasis lichenoides et varioliformis acuta (PLEVA). PLEVA is characterized by skin lesions that ulcerate, breakdown, form open sores, then form a red-brown crust. FUMHD often begins as PLEVA, but then rapidly and suddenly progresses to large, destructive ulcers Livedoid vasculopathy is a clinical diagnosis, supported by skin biopsy of a red papule or the edge of a new ulcer. Histopathology reveals hyalinisation, thickened blood vessel walls, fibrin deposition, vascular occlusion by thrombosis and minimal inflammation. Direct immunofluorescence often shows deposition of immunoglobulin and complement.
Skin lesions of cutaneous lupus erythematosus can be subdivided into: Lupus-specific changes. Clinical signs diagnostic of, or unique to, LE. Histology is diagnostic for LE; vacuolar interface dermatitis. Lupus-nonspecific changes. Clinical signs found not only in LE, but also in other connective tissue diseases Pityriasis lichenoides et varioliformis acuta (PLEVA), or Mucha- Habermann disease, presents as a sudden onset of erythematous macules, papules, and papulovesicles in children or young adults that appear in patches from a few to over 100 lesions Professor of Pathology Oakland University William Beaumont School of Medicine Outline •Mycosis fungoides (MF)/Sézary syndrome •CD8+ CTCL •Mimics of MF -Lymphomatoid lichenoid keratosis -Lymphomatoid drug eruption -Pigmented purpuric eruption.

Pityriasis lichenoides chronica (PLC) is a skin disease that causes the development of small, scaling, raised spots on the skin.PLC is the relatively mild form of the disease pityriasis lichenoides.A person with PLC tends to have multiple episodes of papules on the skin lasting for months or a few years, meaning the disease is chronic Erythema, scaling, and a variable degree of atrophy are the major characteristics of parap-soriasis; crops of spontaneously regressing erythematous papules characterize pityriasis lichenoides. Small plaque parapsoriasis has a benign course. Pityriasis lichenoides et varioliformis acute (PLEVA) is characterized by crusted vesicular or.

Methods: We reviewed our cases of non-neoplastic skin conditions with large, CD30-positive cells and searched the literature for similar cases. Results: A total of 28 cases were included in the study.
