The Retinoblastoma Gene

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...

Multipotency of Hematopoietic Stem Cells

Multipotency of Hematopoietic Stem Cells

The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...

Area of Science:

Dermatology
Rheumatology
Pathology

Background:

Multicentric reticulohistiocytosis (MRH) is a rare non-Langerhans cell histiocytosis characterized by systemic involvement.
Cutaneous manifestations are common in MRH, often presenting as papules or nodules.
Polyarthritis is a frequent systemic feature, impacting joint function.

Observation:

A unique case of MRH from India is presented, highlighting its clinical presentation.
The patient exhibited multiple, mildly pruritic cutaneous nodules on the face, ears, elbows, wrists, knees, and hands.
Joint involvement included polyarthritis affecting both small and large joints.

Findings:

Histopathological examination confirmed the diagnosis of multicentric reticulohistiocytosis.
The cutaneous lesions and polyarthritis demonstrated a self-resolving course.
Complete resolution of all lesions was observed within 1.5 years.

Implications:

This report expands the geographic understanding of multicentric reticulohistiocytosis.
The case underscores the potential for spontaneous remission in MRH.
Further research into the natural history and treatment of MRH is warranted.
