Summary
Multicentric reticulohistiocytosis is a rare systemic disease causing painful nodules and arthritis. Histopathology confirmed this rare condition in a 55-year-old female patient.
Area of Science:
- Rheumatology
- Dermatology
- Pathology
Background:
- Multicentric reticulohistiocytosis (MRH) is a rare, systemic granulomatous disease with unknown etiology.
- It affects multiple organs, including skin, joints, and internal organs, presenting with characteristic histopathology.
Observation:
- A 55-year-old female presented with multiple painful nodules on extremities, neck, and back.
- Lesions were predominantly periarticular, associated with arthropathies and smaller nodules on ear helices.
- No other significant clinical or investigative abnormalities were noted.
Findings:
- Histopathological examination confirmed the diagnosis of multicentric reticulohistiocytosis.
- The distinct histopathology is key to diagnosing this rare granulomatous condition.
Implications:
- Early diagnosis and management of MRH are crucial for preventing joint destruction and systemic complications.
- Further research into the etiology and pathogenesis of MRH may lead to targeted therapies.
- This case highlights the importance of considering rare diseases in the differential diagnosis of patients with polyarthritis and cutaneous nodules.

01:20The 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,...

01:03Rous 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...

01:19Multipotency 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...
01:27Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
