Summary
A persistent plaque on a 74-year-old man
Area of Science:
- Dermatology
- Pathology
Background:
- A 74-year-old male presented with a decade-long history of a left buttock plaque.
- Previous biopsy under plastic surgery for suspected psoriasis yielded nonspecific histology.
Observation:
- The lesion persisted for 10 years.
- Initial histological examination was inconclusive.
Findings:
- The case required further clinical assessment and repeat biopsies.
- Diagnosis was challenging due to nonspecific initial findings.
Implications:
- Highlights the importance of thorough dermatological evaluation for chronic lesions.
- Underscores the role of repeat biopsies when initial histology is indeterminate.

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

01:30Atherosclerosis I: Introduction
144
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
44
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

01:30Peripheral Artery Disease I: Introduction
58
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

35
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
