Swollen Hands-What’s Biting?

A 64-year-old woman with a history of basal cell carcinoma presents to the dermatologist for skin cancer surveillance. She is incidentally noted to have bruising on her upper eyelids (above). On questioning, she reports experiencing recurrent intermittent eyelid bruising for several years. She denies a history of trauma to her face, pain, or other associated symptoms.

Her medical history is significant for hyperlipidemia, hepatitis C (diagnosed >30 years earlier), osteoporosis, celiac disease, and idiopathic proteinuria for several years. Her surgical history includes appendectomy and carpal tunnel repair.

Pertinent family history includes her mother dying of multiple myeloma and her father of complications of diabetes.

Review of systems is significant for vague symptoms of gastrointestinal discomfort. On more directed questioning, she reports the eyelid purpura is temporally related to the Valsalva maneuver/ strained bowel movements. Her medications include atorvastatin, risedronate sodium, a daily multivitamin, calcium, vitamin D, and aspirin.

Her examination reveals no bruising elsewhere and no findings of interest on skin or mucous membranes.

B. Allergic contact dermatitis, purpuric type

Eyelid bruising was observed on a 64-year-old woman during routine skin cancer follow-up. She denied trauma or pain. What does this look like to you?

The right-sided groin swelling shown below is soft and compressible. It is unclear whether the testicle is contained within the affected hemiscrotum.

A compressible groin swelling is the only abnormal feature after full-term gestation and unremarkable delivery. Your Dx?

This intensely itchy, blistering rash on the forearms and upper chest of a 13-year-old girl occurred after a day at the beach. The girl had polymorphic light eruption (PMLE), the most common abnormal reaction to UV light.

A. PMLE classically presents as a papular or papulovesicular eruption on the arms and anterior chest

B. The reaction usually begins 12 to 24 hours after an initial exposure to light of a suddenly increased intensity

C. Some parts of the body are severely involved while similarly exposed areas are paradoxically spared

D. The rash resolves after 7 to 10 days, often leaving whitish scarring

What are the characteristics of this blistering rash caused by exposure to UV light? 

Intensely Pruritic Rash After Sun Exposure in a Tween Girl 

A 5-year-old boy with a history of atopic dermatitis since 6 weeks of age, presents with a rash around his mouth that has been present for approximately 1 year. The patient’s mother reports that desonide topical cream was applied to the affected area for about 5 days, which initially resulted in improvement, however the rash returned after this medication was discontinued. The rash also recently improved after the patient took amoxicillin for an infection. She also notes that the patient has been licking his lips more frequently.

On examination there is an erythematous papulopustular eruption restricted to the perioral region, with sparing of the vermillion border. Mild hyperpigmentation is noted on the patient’s neck. There is no active involvement of other areas of the body.

The eruption has been present for 1 year and is restricted to the perioral region. What is included in your differential?
