Skin Cancer

3.0K
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.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Chronic Pancreatitis I: Introduction

59
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Chronic Pharyngitis01:23

Chronic Pharyngitis

829
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Area of Science:

  • Ophthalmology
  • Oncology
  • Dermatology

Background:

  • Sebaceous carcinoma is an aggressive eyelid cancer.
  • It often presents as benign conditions like chalazion, delaying diagnosis.
  • Delayed diagnosis increases risks of morbidity, mortality, and metastatic disease.

Purpose of the Study:

  • To report a case of sebaceous carcinoma mimicking chalazion.
  • To emphasize the importance of high clinical suspicion for early diagnosis.
  • To highlight the association with Muir-Torre Syndrome.

Main Methods:

  • Diagnosis via excisional biopsy after failed conservative chalazion treatments.
  • Conjunctival map biopsies to rule out local spread.
  • Orbital MRI and whole-body PET scan to assess for metastasis.

Main Results:

  • Excisional biopsy confirmed sebaceous carcinoma.
  • Imaging studies showed no evidence of metastatic disease.
  • Wide local excision resulted in no recurrence at 1-year follow-up.

Conclusions:

  • Sebaceous carcinoma requires a high index of suspicion when presenting as recalcitrant chalazion.
  • Prompt diagnosis and complete excision are vital for favorable outcomes.
  • Awareness of Muir-Torre Syndrome is important for comprehensive patient management.
