Summary
This case study details a rare presentation of verrucous cutaneous sarcoidosis in an elderly woman. Diagnosis requires excluding other granulomatous conditions, with various treatments available.
Area of Science:
- Dermatology
- Pathology
Background:
- Cutaneous sarcoidosis affects up to one-third of sarcoidosis cases.
- Lesion presentation in cutaneous sarcoidosis is highly variable.
Observation:
- A 77-year-old woman presented with erythematous and hyperpigmented macules on her arms and legs.
- She also had erythematous, hyperkeratotic nodules, some crateriform, on her lower legs and feet.
Findings:
- The patient exhibited a rare form of cutaneous sarcoidosis, specifically verrucous sarcoidosis.
- Diagnosis was confirmed via clinical and histopathologic exclusion of other granulomatous conditions.
Implications:
- This case highlights the diverse clinical spectrum of cutaneous sarcoidosis.
- Effective management strategies involve a range of therapies, including glucocorticoids, antimalarials, tetracyclines, and methotrexate.

01:30Skin 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.

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...

01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:15Reticular Dermis
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

01:29Cardiomyopathy IV: Restrictive Cardiomyopathy
Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...
