Summary
A growing thumb tumor in a 71-year-old woman was diagnosed as gouty tophus. This case highlights the importance of considering tophaceous gout in dermal growths.
Area of Science:
- Dermatology
- Rheumatology
- Pathology
Background:
- Tophaceous gout, a manifestation of chronic hyperuricemia, can present as subcutaneous nodules.
- Dermal involvement is less common but can mimic other skin lesions.
Observation:
- A 71-year-old female presented with a gradually enlarging, asymptomatic dermal tumor on her thumb.
- Clinical examination revealed a firm, non-tender nodule.
Findings:
- Diagnostic workup including ultrasound and histology confirmed the presence of a gouty tophus.
- Laboratory investigations supported the diagnosis of gout.
Implications:
- This case underscores the need for considering gouty tophi in the differential diagnosis of thumb tumors.
- Early recognition and management of tophaceous gout are crucial to prevent further complications.

01:27Goiter
Goiter refers to an abnormal enlargement of the thyroid gland that may appear as a diffuse goiter (uniform enlargement) or nodular (single or multiple nodules). Functionally, it is classified as nontoxic (normal/low hormone levels) or toxic (excess hormone production).PathophysiologyDiffuse thyroid enlargement typically results from prolonged stimulation by thyroid-stimulating hormone (TSH) or TSH-like agents, commonly seen in hypothyroidism or iodine deficiency. In contrast, in hyperthyroid...
01:25Endocarditis II: Clinical Features of Infective Endocarditis
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...
01:31Pulmonary Tuberculosis III
Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

01:29Assessment of the Cardiovascular System II: Inspection
Inspection is the initial step in assessing the cardiovascular system. It involves a detailed visual examination that provides crucial information about a patient's circulatory and cardiac health. This systematic process, conducted from head to toe, helps identify signs of cardiovascular conditions by observing physical appearance, skin and mucous membranes, jugular and carotid pulsations, chest symmetry, and the condition of the extremities.

01:23The Thyroid Gland
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...
