Shiitake mushroom-induced flagellate erythema: A striking case and review of the literature.

We describe a 61-year-old Caucasian man who presented with a pruritic, erythematous eruption of multiple linear streaks on the trunk and extremities starting 1 day after eating raw shiitake mushrooms. His symptoms and skin lesions resolved with minimal hyperpigmentation within approximately 1 week after treating with topical steroids and oral antihistamines. Skin biopsy showed non-specific findings, including a sparse perivascular and interstitial dermatitis as well as focal vacuolar interface changes. Our case illustrates that this condition is a visibly striking dermatitis with a self-limited course. The pathomechanism of the skin eruption remains unclear. PMID: 24021365 [PubMed - in process]

CONCLUSIONS: Because of the broad spectrum of clinical manifestations and the extreme diversity of disease, LCH remains a diagnostic dilemma. Morphological identification of LCH cells and positive immunochemical staining with CD1a, S100, and/or CD207 (Langerin) of lesional cells are necessary for a definitive diagnosis.

Conclusions: The findings presented here support the idea that the lymphocyte migratory mechanism observed in neoplasms is similar to that of inflammatory processes of the skin.

Clinical Pathologic Mismatch in a TNF-α Inhibitor-Associated Drug Reaction J Drugs Dermatol. 2019 Aug 01;18(8):828-830 Authors: O’Brien KF, Maiman RE, DeWitt CA Abstract A 56-year-old Caucasian male with a history of chronic plaque psoriasis, primary sclerosing cholangitis status-post liver transplant on tacrolimus, and ulcerative colitis on infliximab developed a progressive erythematous eruption with associated fatigue, anorexia, myalgias, and arthralgias. On two separate occasions, his skin biopsy demonstrated a lichenoid interface dermatitis (LID). Despite multiple courses of oral predn...

AbstractDigital dermatitis (DD), a common ulcerative disease of the bovine foot causing lameness and reducing productivity and animal welfare, is associated with infection by spirocheteTreponema bacteria. Topical tetracycline, the most common treatment, has inconsistent cure rates; therefore, new therapeutic options are needed. We compared effects of topical oxytetracycline and vitamin D3 on innate immunity in DD-affected skin. Cows with active DD lesions were treated topically with oxytetracycline or vitamin D3 and skin biopsies were collected from lesions. Tissue samples were examined histologically, transcriptional expr...

CONCLUSIONS: This study showed that the distribution of the nickel element concentration in ACD skin tissue was different between the early phase and late phase groups. The nickel element was not present in the Ni aqueous ionic state but bound with certain proteins to form a complex in the stratum corneum in ACD model tissue.

CONCLUSIONS AND CLINICAL IMPORTANCE: To the best of the authors' knowledge, this is the first confirmed case of erysipeloid caused by E. rhusiopathiae in a dog. Clinical resolution was attained with the extended use of antibiotics. After 13 months, no clinical signs had returned. PMID: 31364229 [PubMed - as supplied by publisher]

ShiAbstractDermatologic diagnosis and monitoring have been dependent largely on visual grading. A skin biopsy is performed in case of diagnostic uncertainty, but can be traumatic, and results are delayed due to time for specimen transport and processing. Biopsies also destroy specimens, prohibiting lesion evolution monitoring. In vivo reflectance confocal microscopy (RCM) offers a diagnostic alternative to skin biopsy. RCM cap...

In conclusion, in the presence of clinical suspicion, dermal granulomata in ill-formed coalescent morphology with high plasma cell density in a diffuse arrangement are positive factors for the diagnosis of CL, especially when the discernible Leishmania amastigotes are absent. Resource utilization such as polymerase chain reaction and other ancillary techniques during the diagnosis of CL can be minimized by using a range of histopathological features and special attention should be focused on this in the future.
