An unusual case of extra-nodal interdigitating dendritic cell neoplasm: sarcoma or not?

Introduction: Interdigitating dendritic cell sarcoma (IDCS) represents an extremely rare neoplasm frequently originating from T-cell- associated dendritic antigen-presenting cells normally populating the paracortex of lymph nodes. Diagnosis is challenging due to the rarity of this neoplasm and the overlapping features with the other primary and metastatic spindle cell neoplasm, even more, when localized in an extra-nodal site.

Patients And Methods: Herein we report a case of 48 Years old woman with a six-month history of centimetric, quiet painful mass of the philtrum without other significant comorbidity.

Distinct activation of the sympathetic adreno-medullar system and hypothalamus pituitary adrenal axis following the caloric vestibular test in healthy subjects.

Introduction: The vestibular acute stress induces reversible alert-like reactions that involve the sympathetic adrenal-medullar system and hypothalamic-pituitary-adrenal axis responses. The present study aimed to evaluate salivary α-amylase and salivary cortisol production in relation with cardiovascular reactivity induced by acute stress in healthy subjects.

Material And Methods: Forty-eight young healthy male volunteers were examined under basal conditions and at various times after reaching the maximal nystagmic reaction following air caloric vestibular test.
