Case 1:
A 28-year-old female patient presented with a dark nodule on the
umbilicus. She didn’t report pain, bleeding, discharge, or trauma and
denied recent fever or weight loss. Past medical history was consistent
with Wilson’s disease with cirrhosis and hyperkinetic extrapyramidal
symptoms. She was entirely dependent on her mother for daily activities.
Clinical examination revealed a firm, keratotic, black nodule protruding
out of the umbilicus, measuring 2 x 1 cm (Figure 1A). The surrounding
skin was otherwise normal. Gentle traction of the nodule using dermal
forceps allowed its extraction (Figure 1B). The underlying skin didn’t
show signs of inflammation. Histopathological examination revealed
laminated keratin (figure 1C). The diagnosis of omphalolith was made.
Proper hygiene was advised.
