Interface Dermatitis (interface + dermatitis)
Selected AbstractsSubacute cutaneous lupus erythematosus with bullae associated with porphyria cutanea tardaJOURNAL DER DEUTSCHEN DERMATOLOGISCHEN GESELLSCHAFT, Issue 3 2007Wiebke K. Peitsch Summary A 58-year-old patient presented with both annular and polycyclic as well as vesicular lesions. Histology revealed an interface dermatitis with focal hyperkeratosis and subepidermal blistering. Antinuclear antibodies were elevated (1 : 1280) and autoantibodies against Ro-SS-A were found. Based on these findings we made a diagnosis of subacute cutaneous lupus erythematosus (SCLE) with blister formation. Additionally, we diagnosed porphyria cutanea tarda (PCT) triggered by alcohol abuse. Treatment with systemic corti-costeroids and low-dose hydroxy-chloroquine led to rapid resolution of the skin changes. SCLE with blister formation is a rare cause of bullous skin eruptions and has to be distinguished from bullous autoimmune diseases as well as from bullous SLE. Recognition of concomitant PCT, which may be associated with all forms of LE, is especially important because of the therapeutic implications, since a reduced dosage of antimalarials is required.

[source] Cutaneous histopathological findings of Aicardi,Goutières syndrome, overlap with chilblain lupusJOURNAL OF CUTANEOUS PATHOLOGY, Issue 8 2008Athanassios Kolivras We report a 2-year-old girl with developmental delay who, from the age of 1 year, developed perniotic lesions of the hands and feet initially diagnosed as chilblain lupus. Histological examination showed features of epidermal necrosis with intraepidermal bulla formation, interface dermatitis, lymphocytic vasculitis with fibrinoid necrosis and thrombi formation, both superficial and deep dermal lymphocytic infiltrate, lymphocytic eccrine hidradenitis and absence of marked dermal edema. Subsequent investigations suggested a clinical diagnosis of Aicardi,Goutières syndrome (AGS), a rare genetic leukoencephalopathy. Recently, both AGS and familial chilblain lupus, an autosomal dominant form of systemic lupus erythematosus (SLE), have been shown to be allelic thus suggesting a common pathogenic basis. In addition, a phenotypic overlap is apparent between SLE and AGS. To our knowledge, this is the first comprehensive dermatopathological report of the cutaneous lesions seen in AGS, and our paper highlights the importance of considering AGS in the differential diagnosis of perniosis and chilblain lupus. [source] Secondary Syphilis Presenting as Cutaneous T-Cell Lymphoma in an HIV-Positive PatientJOURNAL OF CUTANEOUS PATHOLOGY, Issue 1 2005A. Laungani We present the case of an HIV-positive 38-year-old Caucasian male with a history of fevers, chills, and disseminated nonpruritic erythematous papules that began on his abdomen. An initial skin biopsy revealed a lymphohistiocytic infiltrate at the dermoepidermal junction, exocytosis of atypical lymphocytes, and minimal spongiosis. Immunohistochemistry showed increased CD8-positive cells but only scattered CD30-positive cells. PCR analysis demonstrated T-cell receptor gamma gene rearrangement. RPR, blood and tissue cultures were all negative. The patient was thought to have a cytotoxic cutaneous T-cell lymphoma. Over time, the lesions progressed to the palms and soles and the patient remained febrile. Repeat biopsy demonstrated a lichenoid interface dermatitis with a superficial and deep perivascular, interstitial, and periadnexal lymphohistiocytic infiltrate and the formation of epithelioid granulomas throughout the dermis. The epidermis showed blurring of the dermoepidermal junction, spongiosis, and exocytosis of lymphocytes and neutrophils. Few spirochetes were demonstrated by Steiner stain. Repeat RPR and FTA-Abs serologies were positive. The patient was diagnosed with late secondary syphilis and was successfully treated with benzathine penicillin. This case demonstrates that atypical lymphoid infiltrates can simulate mycosis fungoides in an HIV-positive patient with secondary syphilis and also reiterates that syphilis is a great mimicker of other entities. [source] Intertriginous epidermal dysmaturation from pegylated liposomal doxorubicinJOURNAL OF CUTANEOUS PATHOLOGY, Issue 9 2003Joseph C. English III Background:, A new formulation of doxorubicin (pegylated liposomal doxorubicin) has been developed to attenuate the systemic side effects produced by this agent. Although pegylated liposomal doxorubicin has a much lower risk for cardiotoxicity, it has been associated with cutaneous side effects that differ from, and may also be more frequent than, those produced by the free form of the drug. Methods:, We report a case of interface dermatitis with keratinocyte dysmaturation, limited to the intertriginous areas, in a patient who received pegylated liposomal doxorubicin, and we review the literature. Results:, It is possible that the enhanced delivery of doxorubicin in liposomal form promotes cutaneous side effects of the drug. We consider the possible mechanisms for keratinocyte dysmaturation produced by this form of doxorubicin. Conclusions:, Our findings further suggest that inflammatory changes seen on biopsy may not always allow a reliable histopathologic distinction between this chemotherapy effect and graft-versus-host disease. [source] Paraneoplastic pemphigus: a review of the literatureORAL DISEASES, Issue 4 2000CM Allen Paraneoplastic pemphigus is a relatively rare but highly significant acquired mucocutaneous disorder. The condition typically presents in patients with previously diagnosed lymphoreticular disease, primarily malignancies (non-Hodgkin's lymphoma; chronic lymphocytic leukemia).Multiple sites of involvement are common, with the skin affected by a polymorphous eruption that includes lichenoid plaques as well as bullae. The oral lesions occur in all cases and present as painful widespread shallow ulcers with hemorrhagic crusting of the lipS. Conjunctival involvement is also seen and may result in scarring. Pulmonary lesions are an ominous sign. Histopathologically, intraepithelial and subepithelial clefting associated with interface dermatitis are seen. A variety of autoantibodies directed against desmoplakins and desmogleins can be identified with immunoprecipit-ation studies. Treatment with immunosuppressive agents may result in some resolution of the disease, but the prognosis for paraneoplastic pemphigus is considered to be poor.
