A 43-year-old man presented with well-defined purple to skin-colored 2X1cm sized plague and various sized papules on the posterior neck. Histopathological findings were follicular and perifollicular inflammation with plasma cells, lymphocytes and neutrophils and dermal fibrosis shown as hypertrophic scar tissue. The patient was diagnosed as acne keloidalis nuchae and treated by surgical excision. We report a case of acne keloidalis nuchae showing typical clinical and histopathological findings.

A 24 year old man presented a large keloidal patch on the posterior thigh with persistent purulent fistulae and comedones on it. Histopathological findings showed folliculoperifolliculitis with polymorphs, lymphocytes, plasma cells, multinucleated giant cells and hypertrophic sclerotic connective tiasue. Clinically and histopathologically the diasgnoais of folliculitis keloidalis was made, which is known to develop mostly on the posterior neck. The lesion was treated by surgical excision and skin graft.

Perifolliculitis capitis abscedens et suffodiens is a rare chronic recalcitrant follicular disorder which clinically presents itself as pulstules, nodules, intercommunicating abscess and sinuses that leave atrophic, hypertrophic or keloidal scars. Although the etiology of this of condition is unknown, its association with acne conglobata and hidradenitis suppurativa, collectively termed the follicular occlusion triad, suggest a cammon basic pathogenic mechanism of follicular retention. The therapeutic problem is reflected in the variety of therapies that have been tried with varying degrees of success. We report a case of a 34-year-old man who showed a patch of alopecia on the vertex of his scalp. Clinically, the scalp showed multiple soft fluctuant elevated nodules with nonscarring alopecic patches. We performed a treatment with isotretinoin(13-cis-retinoic acid) during 6 months. The patients clinical appearance was much improved and local recurrence and hair loss have not been observed to date.

We report three cases of acne keloidalis nuchae which showing typical clinical and histopathological findings. A 61-year-old man showed well-defined child-fist sized erythematous to skin-colored hard plaque on his posterior scalp since two years ago and was treated by surgical excision and skin graft(STSG). A 22-year-old man showed discrete pinkish to erythematous pea sized follicular papules and pustules on his occiput since seven years ago and was treated by intralesional injection of triamcinolone for several times with fair response. Finally, a 38-year-old black man showed variable sized hard round follicular papules on his posterior scalp with several grouped hairs on the center of papules and was treated by intralesional injection of triamcinolone effectively. Histopathologically, common findings were follicular and perifollicular inflammation with the infiltration of plasma cells, neutrophils, lymphohistiocytes, massive dermal fibrosis resembling scar tissue, and diminished sebaceous glands.

BACKGROUND: In the treatment of keloids, the recurrence after surgical excision is relatively high. Various types of adjuvant therapy such as radiotherapy and corticosteroid injection have been used to reduce the recurrence. OBJECTIVE: The aim of this study was to determine the appropriate time for initiating postoperative radiotherapy and to analyze factors associated with the occurrence and recurrence of keloids. METHODS: Of these 37 lesions, 22 were located in the ear lobe, 6 in the helix of the auricle, 4 on the shoulder, 3 on the chest wall, and 2 on the abdomen. Causative factors were piercings (n=24), trauma (n=5), previous surgical lesions or bacillus Calmette-Guerin vaccination lesions (n=3) and acne (n=2). Radiation therapy was initiated within 24 h in 24 lesions, between 24 and 72 h in 6 lesions, and after more than 72 h in 7 lesions. RESULTS: Seven lesions recurred, including 5 recurrences in high stretch-tension regions (p=0.010). Initial treatments were administered within 24 h in 1 lesion and more than 72 h after surgical excision in 6 lesions (p<0.0001). In the 19 patients with family histories, maternal and paternal genetic predispositions were present in 14 and 5 patients, respectively (p=0.033). CONCLUSION: Radiotherapy should be initiated within 72 h of surgical excision. Location in a high stretch-tension region was significantly associated with recurrence. Patients with a family history showed a significant tendency toward maternal genetic predisposition. Therefore, combination therapy should be considered to reduce the occurrence and recurrence of keloids, and careful observation is required.

Keloids result from excessive production of fibrous tissue during an abnormal wound healing process. Keloids can occur after trauma, and trauma can range from laceration, piercing, bites, surgery, and burns, to other skin conditions such as acne or folliculitis. We present a case of 68-year-old man, which was characterized with a relatively firm, non-tender, mild pigmented mass in his right earlobe. We performed a local excision, together with microscopic analysis. The mass was eventually diagnosed as a keloid scar in the right earlobe. Postoperative adjuvant pressure therapy using magnets was adopted and the postoperative follow-up was maintained without any recurrence. Auricular keloids should be considered in the differential diagnosis regardless of the cause or the age of patient.

A case of acne conglobata associated with hidradenitis suppurativa, dissecting cellulitis and disseminated superficial actinic porokeratosis in 44 year-old man is presented with brief review of literature. The patient had acne vulgaris for a few years during his highschool days, about 5 years prior to the development of such a typical lesions of acne conglobata as multiple comedones, papules, pustules, abscesses, cysts and draining sinnses and subsquent hypertrophic scars and keloids. We are ps,rticularly interested in association of hidradenitis suppurativa and dissecting cellulitis with ance conglobata that comprise follicular occlusion triad in tbis teint. The pstient was treztei with systemic antibiotics and corticosteroids injections and surgical interventions with considerable improvement.

BACKGROUND: Keloids may occur at any age, but tend tend velop between the ages of 10 and 30. The incidence and median age of onset are equal for both sexes. Keloids are common among the darker pigmented rices, but there have been a few clinia studies of keloids in Korea. OBJECTIVE: The purpcse of this study was to evaluate the variable clinical characteristics of keloids in Korea. METHODS: This clinical investigation was made with 223 of patients of keloid who had visited the Department of Derrnatology, Chonnam University Hosptal from January 1984 to December 1993. RESULTS: 1.The annual incidenie averaged over 10 years was 0.831 (361 cases of total 43,752 outpatients). 2.The ratio of male to female was 1: 0.94(Male. 115, Feila 108). 3.The mean age of the onset and at the first visit to our hospital were 24.5years and 29.2 years respectively. 4.In our series tte presternal area was the most commor saes, the shouder region next. Most keloids on the shoulder were related to BCG vaccination in ifoncy or chilhood. 5.The precipitating fa ctors associated with keloid were riaeeding dermatologic diseases(33.2 %), unknown(17.9%) rejection & vaccination(15.2%), operation(13.9%), burn(13.9%) and laceration(5.8%) in descending order. 6.Among preceeding as, iociated dermatologic diseases, acne w s the most common. 7. A positive family history is more likely in cases of mitile keloidal (p<0,001), and severe keloidal formation. 8.Most patients did not. complain of any symptorns(45.3%) nd a symptom of pain or tenderness(40.8%) was piesert rather than pruritus(13.9%). 9.The most prevaent tr eatment modality was intralesional injection with triamcinolone acetonide (84.3%). CONCLUSION: According, to this study, usually keloids occore in patients between 10 and 29 years of age, and most keloids were located on the antetio partion of the chest, shoulders, and face and scalp. A positive family history is more likely in as of multiple, severe keloidal for mation.

Mesotherapy was first introduced in France by Pistor in 1952. This is a widely used technique of intradermal or subcutaneous microinjections of a highly diluted drug, or cocktail of drugs. The use of mesotherapy is commonplace in medicine, especially in painful disorders of the locomotory apparatus. The technique has also been employed in cutaneous affections and esthetical conditions such as keloids and hypertrophic scars, acne, psoriasis, vitiligo, wrinkles, alopecia areata and hair loss, cellulitis, lipodystrophy, obesity, telangiectasias, lymphedemas, peripheral vascular diseases, and leg ulcers. A 24-year-old woman presented with painful eczematous subcutaneous nodules located at the points where mesotherapy had been applied. Histologically, it showed panniculitis with acute inflammation, aggregation of neutrophils, and fat necrosis. We report an unusual case of panniculitis after mesotherapy.
