Secondary Lymphoid Organs

Secondary Lymphoid Organs

Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
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...

Accessory Structures of the Eye

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Primary Lymphoid Organs

Primary Lymphoid Organs

Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
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...

Summary

Orbital lymphoma can mimic orbital cellulitis, presenting a diagnostic challenge. Early diagnosis requires a multidisciplinary approach including imaging and biopsy for effective management of this rare orbital malignancy.

Background:

Orbital lymphomas, predominantly non-Hodgkin type, can arise from various orbital structures.
Orbital malignancies frequently present atypically, posing diagnostic challenges for clinicians.

Observation:

A 66-year-old male presented with acute painful proptosis and visual loss in the left eye.
Initial symptoms included proptosis, eyelid swelling, restricted eye movements, and conjunctival congestion, mimicking orbital cellulitis.
Despite treatment with antibiotics and steroids, the patient showed no improvement.

Findings:

Contrast-enhanced computed tomography (CECT) revealed orbital lymphoma involving maxillary and ethmoid sinuses.
Histopathological examination confirmed non-Hodgkin lymphoma.

Implications:

Orbital malignancies can masquerade as common orbital infections like cellulitis.
A multidisciplinary approach combining ENT consultation, radiological imaging (CECT), and histopathological biopsy is crucial for accurate diagnosis and timely management of orbital lymphoma.
