Primary Lymphoid Organs01:16

Primary Lymphoid Organs

16.4K
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...

Cranial and Spinal Meninges01:19

Cranial and Spinal Meninges

4.6K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Secondary Lymphoid Organs01:15

Secondary Lymphoid Organs

10.0K
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...

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

7.8K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Cranial Bones: Superior and Posterior View01:14

Cranial Bones: Superior and Posterior View

8.4K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Veins of Head and Neck01:19

Veins of Head and Neck

6.6K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Area of Science:

  • Oncology
  • Dermatopathology

Background:

  • Scalp swelling can present with various etiologies.
  • Diffuse large B-cell lymphoma (DLBCL) is an aggressive non-Hodgkin lymphoma.
  • Primary cutaneous lymphomas are uncommon but require accurate diagnosis.

Purpose of the Study:

  • To report a case of primary cutaneous diffuse large B-cell lymphoma presenting as a long-standing scalp swelling.

Main Methods:

  • A 49-year-old female patient with a one-year history of progressive frontal scalp swelling.
  • Incisional biopsy of the scalp lesion.
  • Histopathological examination of the biopsy specimen.

Main Results:

  • Histological examination revealed diffuse large B-cell lymphoma.
  • The tumor cells exhibited characteristic morphology and immunophenotype of DLBCL.

Conclusions:
