Baldwin has interests in acne, rosacea, keloidal scarring, cosmeceuticals, and the skin microbiome.

The study included 34 healthy subjects aged 18 to 74 years who had undergone any ablative or non-ablative energy treatment in the last three months or had a history of hypertrophic or keloidal scarring.

Lobomycosis was first described in 1931 by Jorge Lobo in a 48-year-old man who lived in the Brazilian Amazon and for the previous 19 years had had keloidal nodules in the lumbar region (8).

Patients with a history of photosensitive diseases, active vitiligo, active psoriasis, and keloidal tendency and those on isotretinoin treatment were excluded from PDL group, and those with a history of hypersensitivity to C.

Application of liquid nitrogen to keloid tissue results in freeze destruction of keloid tissue.16 Cryotherapy has been used for smaller lesions, but its use is limited by considerable pain and sometimes prolonged healing following treatment.17 Cryotherapy has been reported to alter collagen synthesis and induce keloidal fibroblast differentiation towards a more normal phenotype.18 Some authors advocate the use of cryotherapy just prior to steroid injection in order to induce edema and thus facilitate steroid injection.

Microneedling is contraindicated in the presence of anticoagulant therapies, active skin infections, collagen injections and other injectable fillers in the previous six months, personal or familiar history of hypertrophic and keloidal scars.

Treatment response of keloidal and hypertrophic sternotomy scars: Comparison among intralesional corticosteroid, 5-fluorouracil, and 585-nm flashlamppumped pulsed-dye laser treatments.

Exclusion criteria were known photosensitivity, pregnancy or lactation, a history of hypertrophic or keloidal scarring, using isotretinoin, and a history of active acne, or active infections.

For a correct diagnosis, it is important to remember that different histologic variations can be present, and seven morphologic patterns have been identified: conventional, hyalinized/hypocellular, staghorn vessel, myxoid, keloidal, nodular fasciitis-like, and hypercellular [8, 28].

Herein, we report a unique case of primary angiosarcoma that developed in what was initially mistaken for an infected keloidal after bilateral breast reduction surgery.

It ranges from the relatively mild cases characterized by recurrent appearance of papules, pustules, and inflammatory nodules, to severe cases of deep fluctuant abscesses, draining sinuses, and keloidal scars.

(A) Microscopically, the excision specimen demonstrated abundant ropy collagen with rare, bland fibroblast-like spindle cells mixed with native smooth muscle and small vessels; (B) at higher magnification, some of the collagen bundles showed a hyaline, keloidal quality.
