During the last year and a half, the COVID-19 pandemic has had a negative impact on residency training in surgical departments. Patients with this type have a uniform clinicopathology. Lymph node involvement might occur in most of the various anatomical forms of lymphoma in the dog, and lymphoma might be more likely to induce multiple or generalised lymphadenopathy 3. Lymphadenopathy is frequently observed in patients with immunoglobulin G4-related disease (IgG4-RD) and sometimes appears as the first manifestation of the disease. Due to its similar appearance on imaging, it is hard to differentiate from primary liver malignancies. However, in a few cases of this type, IgG4+ plasma cells are detected in both the germinal centers and interfollicular zone [12].

The diagnosis of IgG4-RD is characterized by both elevated serum IgG4 (>135 mg/dL) and histopathological features, including a dense lymphoplasmacytic infiltrate rich in IgG4+ plasma cells (IgG4+/IgG+ plasma cell ratio >40%). Causes include viral and bacterial infections and cancers that affect the lymph nodes. Indeed, lymph node biopsy may be performed under the suspicion that the lymphadenopathy is a malignant lymphoma or other lymphoproliferative disorder. Like a burglar alarm they are on guard against intrusive antigens. A mixed infiltrate of small lymphocytes, immunoblasts, immature plasma cells, mature plasma cells, and scattered eosinophils is observed (Figure 3). This is medically defined as reactive hyperplasia: when white blood cells and plasma cells (antibody secreting cells) multiply in response to a substance that stimulates their production (antigenic stimulation), causing the lymph node to enlarge. There is no evidence of granulomatous inflammation or epithelial malignancy. After a recent infection, children may develop significant and persistent lymph node enlargements.

In contrast, patients with IPT-like IgG4-related lymphadenopathy show no symptoms suggestive of lymphoid malignancy [13]. Lymphadenopathy: the abnormal enlargement of lymph nodes. Substances carried by lymph reach the nodes; these may be antigenic and cause an immune reaction Bacteria and fungi cause predominantly inflammatory reactions; viruses and drugs cause predominantly immune reactions 4 patterns of reactive hyperplasia have been described, depending on the etiology: follicular, paracortical / diffuse, sinus and mixed A clinical finding indicating that a lymph node is enlarged. Lymph node involvement might occur in most of the various anatomical forms of lymphoma in the dog, and lymphoma might be more likely to induce multiple or generalised lymphadenopathy 3.

On laryngoscopy an irregular fungating mass was seen on the vocal cord with infraglottic extension.
