Patient Case Summary

A 45-year-old woman presented with a few weeks of crural skin erythema which is not tender, elevated or indurated. Lesions grew in size over days. She used some 3-in-1 cream (corticosteroid, antibiotic, antifungal) without improvement. Two days before current presentation, she developed a small "wound" of the similar small lesion as those above and in front of the lower leg, on her right heel which soon became big and transformed into a big blister filled with serous fluid and was surrounded by erythema. The region below this blister is a little edematous, and the talocrural joint is painful with limited range of motion, resulting in an antalgic gait. She had no fever or any other systemic symptoms.

The whitish matter around the blister is a cream she applied.

Discussion

What would be the diagnosis for both kinds of lesions presented? Are those the same disease or different processes?

Similar Cases

17 yo male had 2 small lacerations from a metal saw in Costa Rica. Cut healed, scabbed over according to patient. 12 days later, big painful blisters appeared with serosanguenous fluid, no pus, no redness or pain beyond blister borders. No fever. This is day 4. Any ideas?

An 8-year-old female presents with a complaint of pain in her lower lip for one day. She denies any local trauma. She stated that she woke up in the morning with the lesion. The area is red and erythematous. What is the most likely diagnosis?

Female, 20+, showed up with this skin lesion which grew to be like this during the day. There is a blister with fluid. Before it was just a small spot. She didn't scratch it, no history of allergies, it's the only lesion. This is the second time this has happened, also close to that area but on the other surface of the arm. She also said she started a new job 4 months ago, at a restaurant. Any ideas?

Female, 41 y/o, initially presented as unequal-sized erythema with pruritus on both shanks half a year ago. Then blisters began to form on the lesions and soon turned into aching ulcers. Lesions recovered after using unknown ointment. She came to the doctor because it’s the third time of relapse, and lesions began to extend to both thighs. Biopsy/ANCA/ACA/autoantibodies’ results haven’t come back.
