How should I manage a 54‑year‑old woman with a recurrent painless left upper eyelid swelling (likely chalazion), who is using topical estradiol and wants to switch to a transdermal estradiol patch, and who also reports hair thinning?

Management of Recurrent Eyelid Swelling, HRT Transition, and Hair Thinning

Eyelid Swelling Management

This is almost certainly a chalazion, and you should start with warm compresses and lid hygiene; if it persists beyond 2-4 weeks or enlarges, proceed to intralesional triamcinolone acetonide injection rather than waiting for spontaneous resolution. 1

Initial Conservative Treatment

• Apply warm compresses to the affected eyelid for 10-15 minutes, 3-4 times daily to promote meibomian gland drainage 2
• Perform lid hygiene with gentle massage along the eyelid margin after warm compresses 2
• This recurrent pattern (appearing, resolving, then reappearing) is typical of chalazion natural history 1

When Conservative Treatment Fails (After 2-4 Weeks)

• Intralesional triamcinolone acetonide injection achieves complete resolution in 88-90% of cases, often with a single injection 3, 4
• Subcutaneous injection around the lesion is equally effective and may have fewer complications 4
• This approach is particularly appropriate since the lesion is enlarging over 4 days 3

Critical Red Flags to Exclude

• If this chalazion is unilateral, recurrent, and unresponsive to standard treatment, you must consider sebaceous carcinoma and perform a biopsy 2
• Look specifically for: loss of normal eyelid margin anatomy, focal lash loss (ciliary madarosis), or conjunctival cicatricial changes 2
• The recurrent nature warrants checking thyroid function (TSH, free T4), as subclinical hypothyroidism is associated with recurrent chalazia 5

Hormone Replacement Therapy Transition

Switch her from topical estradiol to a transdermal estradiol patch at 0.05 mg/24-hour (50 mcg/day) applied twice weekly, and you must add micronized progesterone 200 mg orally for 12-14 days every 28 days to protect her endometrium. 6, 7

Estradiol Component

• Transdermal patches are preferred over oral formulations due to lower rates of venous thromboembolism and stroke 6
• Standard dosing: 0.0375-0.05 mg/24-hour patches applied twice weekly 6
• Apply to clean, dry skin on lower abdomen, upper outer arm, or thighs, rotating sites to minimize irritation 7
• Assess symptom control after 2-3 months and titrate if needed 7

Mandatory Progestin Protection

• Micronized progesterone is first-line due to lower cardiovascular and thrombotic risk compared to synthetic progestins 6, 2
• Sequential regimen: 200 mg oral (or vaginal) micronized progesterone daily for 12-14 days every 28 days 6, 2
• This induces withdrawal bleeding; if she prefers to avoid bleeding, use continuous combined patches with both estradiol and levonorgestrel 2
• Failure to add progestin in a woman with an intact uterus will lead to endometrial hyperplasia and cancer 7

Safety Principles

• Use the lowest effective dose for the shortest duration consistent with treatment goals 6
• Continue until average age of natural menopause (45-55 years), then reassess 2

Hair Thinning Evaluation

Hair thinning at age 54 in the context of menopause is likely related to declining estrogen and relative androgen excess; the transdermal estradiol patch may improve this, but you need to assess for other reversible causes first. 2

Workup for Hair Thinning

• Check thyroid function (TSH, free T4) - hypothyroidism causes hair thinning and may explain both the chalazia and hair loss 5
• Assess iron studies (ferritin, iron, TIBC) - target ferritin >40 ng/mL for optimal hair growth
• Check complete blood count to exclude anemia
• Consider checking vitamin D, zinc if dietary deficiency suspected

Management Approach

• The transdermal estradiol you're prescribing may improve hair thinning by restoring hormonal balance 2
• Avoid progestins with anti-androgenic effects if she has significant hypoandrogenism symptoms (low libido, sexual dysfunction), as these can worsen hair thinning 2
• Micronized progesterone is appropriate here as it has minimal anti-androgenic effect 2
• Reassess hair density after 6 months of HRT; if no improvement, consider referral to dermatology for minoxidil or other targeted therapies

Common Pitfall

• Do not assume all hair thinning in perimenopausal women is hormonal - thyroid disease and iron deficiency are frequently missed and easily treatable 5
