Insights
This study reports the first case of a solitary nodular cutaneous lymphoma in a young Doberman Pinscher. The T-lymphocyte cancer was successfully treated with surgery, with no recurrence observed.
Area of Science:
- Veterinary Oncology
- Dermatopathology
- Canine Neoplasia
Background:
- Cutaneous lymphoma in dogs can present in various forms.
- Early and accurate diagnosis is crucial for effective treatment and prognosis.
- T-lymphocyte lymphoma is a significant subtype of canine lymphoma.
Observation:
- An 18-month-old Doberman Pinscher presented with a solitary, erythematous, nodular skin mass on its forelimb.
- Cytologic examination and histopathology confirmed the mass as cutaneous lymphoma.
- Immunohistochemistry identified the neoplastic cells as T lymphocytes (CD3 positive, CD79a negative).
Findings:
- The canine cutaneous lymphoma was a solitary nodular form, originating from T lymphocytes.
- Surgical excision was performed for the mass.
- No tumor recurrence was observed 18 months post-surgery, indicating successful treatment.
Implications:
- This case highlights a rare presentation of canine cutaneous lymphoma in a young dog.
- It underscores the importance of immunohistochemistry in differentiating lymphoma subtypes.
- The successful surgical outcome suggests this may be a viable treatment option for solitary nodular forms.
Abstract:
An 18-month-old male Doberman Pinscher was referred to the Veterinary Medical Teaching Hospital of the College of Veterinary Medicine for an erythemic nodular mass on the right forelimb. The mass was diagnosed as cutaneous lymphoma, based on cytologic examination of a mass aspirate and histopathology. Using immunohistochemistry, the neoplastic cells were positive for CD3 but negative for CD79a, E-cadherin, and pancytokeratin, confirming their origin as T lymphocytes. No tumor recurrence was noted 18 months after surgery. To our knowledge, this is the first report of a solitary nodular form of cutaneous lymphoma in a young dog.

Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
Primary Lymphoid Organs
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...
Skin Cancer
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...
Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
Lymphoid Cells and Tissues
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...
Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
