Neuromas are hyperplasia of axons and associated nerve sheath cells. Cutaneous neuromas are rare. Neuromas can be classified into three types: traumatic neuromas, solitary palisaded encapsulated neuromas, and multiple mucosal neuromas. Traumatic neuromas are tangles of neural fibers and connective tissue that develop following nerve injury. These usually present as a solitary, skin colored or pinkish, slowly growing, palpable and painful firm papule or nodule. A 15-year-old female patient presented a solitary 1.0×0.5 cm sized, pinkish palpable well-demarcated firm subcutaneous nodule on the right third proximal interphalangeal joint. We herein report a case of traumatic neuroma which probably originated from the dorsal digital nerve. (Korean J Dermatol 2013;51(10):821∼824)

Nevus sebaceus is frequently complicated by development of a variety of other benign skin tumors. On the other hand, malignant skin tumors are rarely observed in associated with nevus sebaceous. The most common benign skin tumor developing in nevus sebaceus is trichoblastoma, while the most common malignant skin tumor is basal cell carcinoma. However, cases of squamous cell carcinoma developing within nevus sebaceous are rare. A 42-year-old man presented a solitary 3×3-cm sized hemorrhagic, crusted, verrucous mass on the left occipital scalp, which was congenital. He visited our clinic due to the mass rapidly enlarging over the past 3 years and due to bleeding of the mass in the past 3 months. Histopathologically, the tumor showed typical findings of well-differentiated nevus sebaceus and squamous cell carcinoma. We herein report a case of squamous cell carcinoma developing in nevus sebaceous. (Korean J Dermatol 2014; 52(3):182∼185)

Nevus lipomatosus cutaneous superficialis (NLCS) is an uncommon form of connective tissue nevus, which is manifested principally as the deposition of fatty tissue in the dermis. Lesions almost always arise unilaterally on the thigh or buttock. Although NLCS can affect any region of the skin, only five cases of NLCS on face have been reported. A 48-year-old female presented with a skin-colored, 1 cm sized, soft and edematous plaque on the right malar area. The histopathologic findings showed scattered ectopic fat lobules between collagen fibers in the mid to deep dermis. We herein reported a case of solitary and plaque-shaped NLCS on the malar area.

Clear cell basal cell carcinoma is a rare histological variant of basal cell carcinoma, which is characterized by a variable component of clear cells. We report a case of clear cell basal cell carcinoma in a 53-year-old Caucasian male presented with a red 0.7×0.6 cm sized nodule with central bleeding on left cheek for 2 years. Histological examinations showed multiple dermal tumor lobules nested with basaloid cells of a peripheral palisading pattern. In addition, prominent clear cell changes were observed in the center of large nests. The clear cells showed a single large vacuole in their eosinophilic and granular cytoplasm with eccentric condensed nucleus. The clear tumor cells was stained with periodic acid Schiff and showed incomplete diastase-resistance. Intercellular mucin staining with alcian blue was positive. The tumor was successfully treated with Mohs micrographic surgery and no recurrence has been observed for 6 months. (Korean J Dermatol 2013;51(7):548∼551)

Hidradenitis suppurativa is a chronic, relapsing suppurative disease of the apocrine sweat glands that principally affects the axillary and anogenital regions. The etiology of this disorder remains unknown. As conservative treatment usually does not prevent recurrence, surgical treatment is the method of choice, particularly for advanced case. We report a 25-year-old male patient who presented with a 7-year history of abscesses with foul-smelling discharge from his axilla. After failed medical therapy, he was referred for surgery. We performed a wide excision of the axilla with a split thickness skin graft after 1 week. The patient has been doing well, and there has been no relapse for about ayear after the operation.

Eccrine poroma is a benign neoplasm, arising from the eccrine sweat duct. It generally occurs in middle aged individuals and is most commonly found on the sole or the sides of the foot, followed by the hands and fingers. It presents as a solitary, soft or a rather firm consistent, sessile or often slightly pedunculating, tumor. A 47-year-old woman presented with a 2.5×1.5 sized brownish to erythematous pedunculating mass on the left flank. According to histopathologic finding and immunohistochemical staining (epithelial membrane antigen), the final diagnosis was consistent with eccrine poroma. We report here on an interesting case of eccrine poroma presenting as pedunculating mass on the flank, which is an unusual location. (Korean J Dermatol 2012;50(7):647∼649)

Pincer nail deformity is a nail deformity characterized by a transverse overcurvature of the nail plate, which increases along the longitudinal axis. Many conservative and surgical treatment modalities have been reported. Conservative methods can be difficult to use in cases of severe deformity because of their high recurrence rate. Therefore, surgical techniques, including nail matricectomy or correction of the nail bed, have been preferred in these cases. Matricectomy is generally considered as the surgical treatment of pincer nail deformity because of low recurrence rate in the field of dermatology. However, poor cosmetic results (e.g. narrowing of nail plate) are frequently observed. We present here a case of pincer nail deformity in the left great toe in a 57-year-old man who was treated successfully with widening of the nail bed without matricectomy. This method is an effective surgical technique preserving the nail matrix for the correction of pincer nail deformity. (Korean J Dermatol 2012;50(5): 451∼455)

Despite the prominent advantage of natural dyes, It is difficult to keep or mass produce natural dyes. Natural dyes have limited output compared to chemical dyes. Color cosmetics containing natural dyes is more desirable for consumers preferring naturalistic and environment-friendly products than color cosmetics containing artificial dye. in this study, we assessed anti-oxidation potential, Anti-microbial activity of Curcuma longa L. and made color cosmtics containing Curcuma longa L. Then we evaluated safety and effectiveness to compare with color cosmetics containing artificial dye on the market. The results are as follows. The polyphenol content of 1% Curcuma longa L. were 3.99±1.53mg/g. The flavonoid contentof 1% Curcuma longa L. were 2.12±1.20mg/g. As Anti-microbial activity test results, the clear zone against Staplylococcus aureus was 7mm. The color value of the Curcuma longa L. product are L* 51.44, a* 20.02, b* 55.29 and control product are L* 81.36, a* 19.46, b* 75.21. Seen form H/V/C values, color properties of Curcuma longa L. products were darker and had lower saturation than the control product. Based on these findings, we thought that suggest a possibility in future for development of the color cosmetic containing natural pigment.
