Groin Irritation in Young Male During Heat Wave

Case at a Glance

A 24-year-old male presents with non-pruritic linear skin lesions in the inguinal region following increased ambient temperatures and excessive perspiration.

Patient's Story

The patient reported developing skin irritation in the groin area during an unusually hot weather period. He described maintaining good hygiene with regular showering but noticed the onset of linear lesions resembling superficial cuts in the crease between his thigh and groin, adjacent to the scrotum. The lesions appeared suddenly, with smaller initial lesions healing spontaneously before a larger lesion developed along an existing stretch mark. The patient denied significant discomfort, describing only mild awareness of the lesions without associated pruritus. He reported no systemic symptoms such as fever or malaise.

Initial Assessment

Physical examination revealed linear, non-inflammatory lesions in the inguinal fold consistent with mechanical irritation. The patient appeared systemically well with no signs of secondary infection or widespread dermatological involvement. The lesions' location and morphology suggested moisture-related skin breakdown rather than infectious etiology.

The Diagnostic Journey

The patient initially considered fungal infection as a differential diagnosis and self-treated with topical clotrimazole. He also applied zinc oxide cream (sudocrem) to the affected area. Online consultation suggested moisture-related irritation similar to intertrigo, with recommendations for moisture control measures including talcum powder application.

Final Diagnosis

Moisture-associated skin irritation (intertrigo) secondary to increased perspiration and mechanical friction in the inguinal region.

Treatment Plan

Conservative management with moisture control measures including talcum powder application, continued use of barrier creams (zinc oxide), and maintenance of good hygiene. Patient advised to wear breathable, loose-fitting undergarments and consider preventive measures during periods of high ambient temperature.

Outcome and Follow-up

Patient reported intention to implement suggested moisture control measures and monitor for improvement over the following days. Plan for professional evaluation at sexual health clinic if symptoms persist or worsen.
