Epidermal cell necrosis with direct epidermal infiltration of Epstein-Barr virus (EBV)-encoded small nuclear RNA-positive T lymphocytes in a patient with EBV-associated haemophagocytic syndrome

TEN mimics: Classification and practical approach to toxic epidermal necrolysis-like dermatoses

Toxic epidermal necrolysis (TEN) is an acute life-threatening dermatologic emergency. However, many dermatoses can present with a TEN-like eruption. Those "TEN-mimics" are a true diagnostic challenge and an alarming differential diagnosis to such a serious condition. Herein, we will expose and classify the landscape of TEN-mimics. Also, the key differentiating clinical and/or laboratory points will be highlighted to help an accurate diagnosis of either a TEN or a TEN-like presentation.

Toxic epidermal necrolysis and hemophagocytic lymphohistiocytosis: a case report and literature review

Diagnostic criteria for hemophagocytic lymphohistiocytosis should be reviewed early in critically ill patients with toxic epidermal necrolysis, multisystem dysfunction, and a deteriorating clinical trajectory.

TEN-like eruption in setting of EBV positive T-cell lymphoproliferative disease with HLH, in a child

Haemophagocytic lymphohistiocytosis complicating Epstein-Barr virus positive T-cell lymphoproliferative disease of childhood is a rare and life-threatening entity. We report a child with this condition presenting with a toxic epidermal necrolysis-like eruption.

Dermatopathic lymphadenitis with generalized erythroderma in a patient with epstein-barr virus-associated hemophagocytic lymphohistiocytosis

Here, we describe a patient with Epstein-Barr virus (EBV)-associated hemophagocytic lymphohistiocytosis (HLH) who simultaneously presented with generalized erythroderma and dermatopathic lymphadenitis (DL). A 63-year-old Korean woman presented at our hospital with fever, hepatosplenomegaly, axillary lymphadenopathy, and generalized erythrodermic eruption. The bone marrow biopsy findings were consistent with the diagnosis of HLH, and EBV DNA was detected using the polymerase chain reaction. Based on serologic tests that indicated a primary EBV infection, the patient was diagnosed with EBV-associated HLH. Histopathologic analysis of enlarged lymph nodes was consistent with DL, and EBV-encoded small nuclear RNA-positive mononuclear cells were detected. We assume that activated histiocytes, lymphocytes, and proinflammatory cytokines in HLH may have important roles in the development of generalized erythroderma and DL. Disrupted epidermal/dermal junctions owing to erythroderma may also be involved in the development of DL.
