Itchy Stingy Armpits

A 38-year-old bus driver complains of an uncomfortable rash for the last few days. The rash started at the left axilla gradually three weeks ago and is progressive. The rash is inflammatory, bilateral and involves both axillae. Her physical examination reveals an erythematous round area with a group of vesicles arising from the noninflammatory base and skin erosion in the intertriginous areas. The lesions are pruritic and associated with a stinging and burning sensation, but there is no sign of scar, fissure or pustules, as shown below. These lesions are also worsened when she wears tight shirts and malodorous, particularly after exercise. Her PMH shows a similar reoccurring lesion and spontaneous recovery over the past eight years. Her father and sister have similar lesions that come and go. Which diagnoses are correct,
