Insights

Langerhans cell histiocytosis (LCH) is a rare orbital tumor. This case highlights successful chemotherapy treatment for a multivisceral LCH presentation in an infant.

Area of Science:

  • Pediatric Oncology
  • Ophthalmology
  • Histiocytosis

Background:

  • Langerhans cell histiocytosis (LCH) is a rare neoplastic proliferation of Langerhans cells.
  • Orbital tumors are uncommon in LCH, representing less than 1% of cases.

Observation:

  • An 18-month-old infant presented with left exophthalmos, polydipsia, and polyuria.
  • Imaging revealed an orbital mass with bone destruction and soft tissue infiltration, alongside widespread secondary lesions.
  • Biopsy confirmed Langerhans cell histiocytosis.

Findings:

  • The infant had multivisceral LCH involving the orbit, skull, ribs, skin, liver, and spleen.
  • Chemotherapy with vinblastine and steroids was administered.
  • The child showed a positive response to treatment.

Implications:

  • This case underscores the importance of considering LCH in infants with orbital masses and systemic symptoms.
  • Multivisceral LCH requires prompt and aggressive multimodal therapy.
  • Successful treatment can lead to long-term remission.

Secondary Lymphoid Organs01:15

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...

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...

Lymphoid Cells and Tissues

Lymphoid cells and tissues are integral to the immune system, which is crucial in maintaining our body's defense against harmful pathogens. They form the building blocks of lymphoid organs, which include the spleen, thymus, and lymph nodes.
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...

Liver Histology

The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
Hepatocytes perform a variety of essential functions. They secrete...
Intralumenal Vesicles and Multivesicular Bodies01:38

Intralumenal Vesicles and Multivesicular Bodies

Intraluminal vesicles (ILVs) are small vesicles 50-80 nm in diameter formed during the maturation of early endosomes. A specialized endosome containing numerous ILVs is called a multivesicular body (MVB). ILVs contain internalized molecules such as antigens, nucleic acids, proteins, and metabolites. Some of these molecules are released from the MVBs inside exosomes and are transported to other cells. Other MVBs contain molecules that are retained in the ILVs and are later degraded within the...
