atopic eczema
1st line – 

topical corticosteroid + supportive measures

Use the lowest-potency topical corticosteroid capable of containing disease.

Hydrocortisone is a low-potency topical corticosteroid and is used for mild cases. Triamcinolone is a moderate-potency topical corticosteroid used in moderate/severe cases.

Advise patients to pay attention to personal hygiene. With regard to the genital area, they should: avoid irritants (e.g., antibacterial soaps) and over-washing; avoid common allergens (e.g., perfumes, fragrant soaps, detergents, and fabric softeners).[1][33]

Use soap substitutes (e.g., aqueous cream, emulsifying ointment) once or twice daily and emollients (e.g., petroleum jelly, aqueous creams, lotions) when needed.[1]

Use of a lubricant during sexual intercourse can improve symptoms of dyspareunia.

Affected patients should wear white cotton underwear.

Primary options

hydrocortisone topical: (2.5%) apply sparingly to the affected area(s) twice daily

OR

triamcinolone topical: (0.1%) apply sparingly to the affected area(s) twice daily

Consider – oral antihistamine

Oral antihistamines are useful for patients with significant pruritus.

Hydroxyzine is commonly used, but may cause sedation. Non-sedating options include cetirizine, fexofenadine, and loratadine.

Primary options

hydroxyzine: 25 mg orally every 6-8 hours when required, maximum 100 mg/day

OR

cetirizine: 5-10 mg orally once daily when required

OR

fexofenadine: 60 mg orally twice daily when required, or 180 mg orally once daily when required

Plus – 

topical antifungal

Treatment recommended for ALL patients in selected patient group

Topical antifungals (e.g., ketoconazole, miconazole, clotrimazole) in conjunction with mild or moderately potent topical corticosteroids may be used for more severe cases (i.e., those with significant erythema/inflammation).[1]​ The corticosteroids are typically applied for 2-3 weeks, while the antifungal agent is used until active skin disease resolution is seen.

Seborrhoeic dermatitis is a chronic, frequently recurrent condition, so these medicines are likely to be used intermittently over an extended time period.

Primary options

ketoconazole topical: (2%) apply to the affected area(s) once daily

OR

miconazole topical: (2%) apply to the affected area(s) twice daily

OR

clotrimazole topical: (1%) apply to the affected area(s) twice daily

Topical corticosteroids should be used only for more severe flare-ups with marked inflammation and erythema. Limit use to periods of 2-3 weeks.

When the disease flare-up is under control, the topical corticosteroids should be discontinued and the ketoconazole cream continued as needed (i.e., until skin disease resolution is seen).

Seborrhoeic dermatitis is a chronic, frequently recurrent condition, so these medicines are likely to be used intermittently over an extended time period.

Use hydrocortisone, a low-potency topical corticosteroid, for mild disease and triamcinolone, a medium-potency topical corticosteroid, for moderate disease. Limit use to 2-3 weeks.

Topical calcineurin inhibitors or the vitamin D analogue calcipotriene can be used as an alternative to topical corticosteroids, (and to avoid potential skin atrophy).[1]​ They are used until active skin disease resolution is seen. Be wary of extended use of these drugs in the uncircumcised male. 

Avoid strong crude tar preparations at anogenital sites, as the skin at these sites tends to absorb topical agents, leading to a heightened risk of genital cancer.

Advise patients to pay attention to personal hygiene. With regard to the genital area, they should: avoid irritants (e.g., antibacterial soaps) and over-washing; avoid common allergens (e.g., perfumes, fragrant soaps, detergents, and fabric softeners).[1]​

lichen sclerosus
1st line – 

topical corticosteroid ± antibiotic/antifungal

Apply clobetasol, a high-potency topical corticosteroid, until resolution of active skin disease.[1]​ Its use induces re-modelling of the affected mucosa, relieves phimosis, improves the histological signs, and can avoid the need for circumcision. 

Avoid topical calcineurin inhibitors such as tacrolimus ointment and pimecrolimus cream.[54][55]

Add antibiotics and antifungals as indicated by specific findings of diagnostic testing.

Primary options

Surgical interventions range from circumcision, frenuloplasty, and meatotomy to sophisticated plastic repair, depending on the clinical presentation and the site of greatest disease impact on the organ.

Complete circumcision is the preferred treatment because all affected tissue is removed and any secondary involvement of the glans usually regresses or resolves after the procedure.

Identify and treat underlying disease and address predisposing factors.[1]​ Consider that it may be a secondary opportunistic complication of an underlying dermatosis, especially lichen sclerosus.

The antifungal agent is applied until resolution of active skin disease.

Advise patients to pay attention to personal hygiene. With regard to the genital area, they should: avoid irritants (e.g., antibacterial soaps) and over-washing; avoid common allergens (e.g., perfumes, fragrant soaps, detergents, and fabric softeners).[1]

Use of a lubricant during sexual intercourse can improve symptoms of dyspareunia.

Advise the patient to keep the area as cool and dry as possible and advise wearing undergarments that allow air to circulate (e.g., boxer-type underpants, white cotton underwear).
