Gross inspection revealed proliferative and ulcerative lesions in the mucosa of the base of the tongue, oropharynx, and esophagus in all 3 cases. Proliferative lesions were well-demarcated, white-to-brown, exophytic nodules on the lingual and oropharyngeal mucosa (papillomas, cases 1-3); a well-demarcated, white nodular fibroma in the distal esophageal submucosa (case 1); and locally infiltrative areas of mucosal thickening with ulceration and dark red-to-brown areas of hemorrhage in the base of the tongue and oropharynx (squamous cell carcinomas [SCCs], cases 1-3). Histologically, non-neoplastic lesions were irregular (cases 2, 3) or pseudocarcinomatous (case 1) mucosal hyperplasia with parakeratosis (cases 1-3) and dysplasia (cases 1, 2) in the base of the tongue, oropharynx, and esophagus. Neoplastic lesions were papillomas affecting the base of the tongue, oropharynx, and esophagus (cases 1-3); a submucosal distal esophageal fibroma (case 1); and SCCs affecting the base of the tongue and oropharynx (cases 1-3). Mucosal ulceration was associated with the SCCs in all cases. Inflammation was lymphoplasmacytic. Esophageal vascular myxomatous degeneration or proliferation with fibrosis were present.

Plasma samples underwent protein precipitation followed by chromatographic separation on a reversed-phase C18 column under isocratic elution. The method was validated, assessing linearity, accuracy, precision, recovery, and matrix effects in both cat and dog plasma. The method had high sensitivity, with limits of detection of 0.2 ng/mL for 5-HT, 0.08 ng/mL for KYN, and 2.5 ng/mL for TRP, and limits of quantification of 0.35, 0.22, and 4.2 ng/mL, respectively. Calibration curves showed excellent linearity (<i>R</i>² > 0.995) across biologically relevant concentration ranges. Intra- and inter-day accuracy and precision were within acceptable limits (<15% relative SD). The method had good recovery and minimal matrix effects.

Histologic examination revealed granulomatous enteritis with abundant intralesional acid-fast bacilli and marked inflammation of intestinal and mesenteric vessels that histologically resembled arteritis.

MAP infection was confirmed by Ziehl-Neelsen stain and real-time PCR assay. Verhoeff-van Gieson stain revealed a complete absence of inner and outer elastic laminae, supporting a lymphatic rather than arterial origin.

Agreement for WBC and platelet counts was generally good, although discrepancies were noted for monocyte and mean platelet volume in both species.
