Case of mastocytemia and systemic mastocytosis in a dog: ProCyte Dx and Sysmex XT-2000i scattergram findings, morphologic features, and c-kit somatic mutation analysis.

A 10-year-old female Golden Retriever was presented for a recheck after the complete removal of low-grade complex mammary carcinoma. The in-house ProCyte Dx automated counts revealed moderate regenerative anemia and moderate eosinophilia. The ProCyte Dx WBC scattergram showed a cloud in an unusual place parallel and to the right of the monocyte dot plot location.

A challenging case of lymphoproliferative disease in a cat.

A 7-year-old male castrated Maine Coon cat presented with edema of the right hindlimb and a markedly enlarged right popliteal lymph node. A CBC showed a neutropenia of 1.5 × 10 /μL.

Cytologic features of an acanthomatous ameloblastoma in a dog.

An 8-year-old mixed breed male dog was presented with a mass on the rostral mandibular gingiva that quickly emerged 2-3 weeks prior to presentation. The mass was firm, smooth, well-circumscribed, and approximately 2 × 1 × 0.5 cm in size rostral to the left mandibular canine tooth (304).

Histological tissue healing following high-power laser treatment in a model of suspensory ligament branch injury.

Background: High-power laser therapy gained popularity recently as a regenerative treatment for tendinitis and desmitis in the horse. However, studies evaluating the effects of laser therapy on tissue repair at the histological level in large mammals are lacking.

Objectives: To evaluate the effects of high-power laser therapy on suspensory desmitis healing, using a model of suspensory ligament branch injury.

Computer-assisted mitotic count using a deep learning-based algorithm improves interobserver reproducibility and accuracy.

The mitotic count (MC) is an important histological parameter for prognostication of malignant neoplasms. However, it has inter- and intraobserver discrepancies due to difficulties in selecting the region of interest (MC-ROI) and in identifying or classifying mitotic figures (MFs). Recent progress in the field of artificial intelligence has allowed the development of high-performance algorithms that may improve standardization of the MC.
