Abstract

A 7-month-old female Japanese Black calf developed elongated, nodular mass measuring 30 × 16 cm extended from the retropharyngeal region to mid lateral neck region. Histological examination revealed granulomatous lymphangitis with non-septate fungal hyphae recognized throughout the lesions. Fungal culture, DNA sequencing and molecular phylogenetic tree analysis confirmed the sequence of Lichtheimia corymbifera. The lymphogenous route was speculated to be the main route of fungal spread leading to the characteristic nodular appearance of this case.

摘要

一只7个月大的日本雌性黑牛长成细长的，结节状肿块，从咽后区延伸到颈中外侧区30×16厘米。组织学检查显示肉芽肿性淋巴管炎，在整个病变中都能识别出非纵隔的真菌菌丝。真菌文化,DNA测序和分子系统发育树分析证实了LicheimiaCorymbifera的序列。据推测，淋巴途径是真菌传播的主要途径，导致该病例具有特征性的结节状外观。
