“Why Am I Getting Painful Red Skin Rashes and Bumps That Won’t Go Away?”
By: Dr. Ashley Baldree
A Real Patient Case from Village Dermatology in Katy & Houston, Texas
Skin irritation in areas like the underarms, breast folds, or forearms can be frustrating—especially when symptoms persist for months. At Village Dermatology, we frequently evaluate patients with multiple skin concerns that may seem unrelated but are often connected.
This case highlights a 52-year-old female presenting with red skin lesions and a painful bump, ultimately diagnosed with intertrigo and an epidermal inclusion cyst.
Patient Case Overview
The patient came in with:
Red, inflamed skin lesions on the upper back, forearm, and underarm
A painful bump (cyst) on the forearm and breast
Symptoms present for several months without prior treatment
On examination:
The rash appeared consistent with intertrigo, a condition caused by friction and moisture
The bump was suspected to be an inflamed cyst vs. bug bite, later managed as a cyst
What Is Intertrigo?
Intertrigo is a common inflammatory skin condition that occurs in areas where skin rubs together, especially in warm, moist environments.
Common locations include:
Underarms
Under the breasts
Groin or abdominal folds
Symptoms:
Red, irritated patches
Burning or itching
Possible secondary fungal or bacterial infection
In this case, the patient’s underarm rash was consistent withintertrigo complicated by inflammation and possible fungal overgrowth.
What Is an Epidermal Inclusion Cyst?
An epidermal inclusion cyst is a benign, slow-growing lump beneath the skin filled with keratin.
Key features:
Round, firm bump under the skin
Can become painful, red, or infected
May require excision for complete removal
The patient’s cyst measured approximately 1 cm and caused discomfort, prompting treatment and planned removal.
Treatment Plan and Approach
At Village Dermatology, we take a comprehensive and targeted approach to treat multiple skin concerns simultaneously.
Intertrigo Treatment
Ketoconazole cream (antifungal) applied twice daily
Continued for 1 week after clearing to prevent recurrence
Recommended:
Barrier creams (zinc oxide/petrolatum)
Moisture control and friction reduction
Cyst Management (Forearm)
Vinegar soaks (1:1 vinegar + water) three times daily
Topical mupirocin antibiotic ointment applied after each soak
Cyst on Breast
Observation with plan for surgical excision if persistent
Why Do These Skin Conditions Occur Together?
Many patients are surprised to learn that:
Moisture, friction, and bacteria/fungus often work together to worsen skin conditions.
Intertrigo creates a compromised skin barrier
This environment allows microbial overgrowth
Cysts can become inflamed or infected in similar conditions
When Should You See a Dermatologist?
You should seek evaluation if:
Rashes persist for weeks or months
Skin becomes painful, swollen, or draining
A lump continues to grow or becomes tender
Early treatment can prevent complications and speed healing.
