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 Organs01:16

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...
Leishmaniasis01:30

Leishmaniasis

Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
Skin Cancer01:30

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...
Graves Disease II: Pathophysiology01:24

Graves Disease II: Pathophysiology

Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
Acne Infection01:27

Acne Infection

Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

This study describes a rare case of lichenoid juvenile xanthogranuloma in a 2-year-old boy, characterized by distinctive skin papules and specific cellular findings on biopsy.

Related Experiment Videos

Area of Science:

  • Dermatology
  • Pediatric Pathology

Background:

  • Juvenile xanthogranuloma (JXG) is a common non-Langerhans cell histiocytosis affecting infants and children.
  • While typically presenting as solitary or few xanthomatous nodules, JXG exhibits diverse clinical and histopathological presentations.

Observation:

  • A 2-year-old boy presented with numerous small, flat, yellow-to-brown papules on the face, neck, and trunk.
  • Histopathological examination of the lesions revealed a dermal infiltrate of histiocytes, Touton giant cells, and eosinophils.

Findings:

  • Immunohistochemical analysis showed the infiltrate cells were negative for S-100 and CD1a, but positive for CD68.
  • The absence of systemic lesions and the specific histopathological features supported a diagnosis of a rare variant, lichenoid juvenile xanthogranuloma.

Implications:

  • This case highlights the infrequent lichenoid variant of juvenile xanthogranuloma, emphasizing the importance of thorough histopathological and immunohistochemical evaluation.
  • Recognizing this variant is crucial for accurate diagnosis and appropriate management of pediatric skin conditions.
