Background: Mohs micrographic surgery (MMS) is a precise method of treating skin cancer. There have been many studies about the advantages and disadvantages of MMS. However, no study has yet been carried out regarding the length of surgery. Objective: The purpose of this study was to report our experience with MMS for the treatment of skin cancers and to analyze the operative time of MMS. Methods: We analyzed 50 cases of skin cancers treated by MMS at the Dermatosurgery Clinic in Pusan National University Hospital between April 2009 and November 2009. Results: The minimum and maximum operative times of MMS were 88 and 356 minutes, respectively, and the mean operative time was 171.4 minutes. The mean number of stages was 1.7 (range, 1~4). The mean operative time per stage was 93.9, 62.9, 57.2, and 53 minutes for the 1st, 2nd, 3rd, and 4th stages, respectively. The time percentages for a pathologic consult to the Department of Pathology per stage was 42%, 50%, 52%, and 57% for the 1st, 2nd, 3rd, and 4th stages, respectively; therefore, the consultation to the Department of Pathology occupied a high percentage of the operative time. The mean operative time of repair for surgical defects was 44.4 minutes. Limitations: The results of this study are based on the experience of a single surgical team in a single institution. Conclusion: The results of our study reveal that MMS is a time-consuming operation. Further studies are required to shorten the operation time of MMS.

Amelanotic melanoma is a subtype of malignant melanoma that lacks clinically visible pigmentation. The absence of recognizable pigmentation obscures the clinical hallmark of the more typical form of malignant melanoma. Because it mimics various non-pigmented benign and malignant skin diseases, clinicians have difficulty diagnosing this lesion. An incorrect or delayed diagnosis can result in a worse outcome because the prognosis of melanoma depends on the tumor thickness and tissue invasion at the time of diagnosis. Therefore, early diagnosis is crucial for treating amelanotic melanoma. Dermoscopy is a useful non-invasive technique for diagnosing not only pigmented skin lesions, but also non-pigmented skin lesions because this modality can visualize vascular structures that are not discernible to the naked eye. Analyzing the dermoscopic vascular structures of amelanotic melanoma helps make an early diagnosis. We report here on a case of amelanotic melanoma for which the diagnosis was aided by performing dermoscopy as an adjuvant tool. (Korean J Dermatol 2009;47(5):554~557)

Dermoscopy improves diagnostic accuracy in pigmented and non-pigmented skin tumors by providing magnified visualization of microstructures on the skin. It is also used for general dermatology. In this talk, the speaker will discuss the basics of dermoscopy and recent updates.

Dermoscopy improves diagnostic accuracy in pigmented and non-pigmented skin tumors. Recent reports suggest there is an increase in the rate of dermoscopy use among dermatologists. However, the use in Korean dermatologist seems to be low. In this talk, I will briefly introduce the utility of dermoscopy. Typical cases of benign and malignant tumors will be presented. - Benign melanocytic lesion: Pigment network, streaks, dots/globules, homogeneous blue pigmentation, pseudo-network (face), or parallel pattern (acral glabrous skin). - Seborrheic keratosis: Milia-like cysts, comedo-like openings, crypts, moth-eaten borders, fissures and ridges (brain-like or cerebriform appearance), fingerprint-like structures - Dermatofibroma: Central homogenous area, peripheral pigment network - Vascular lesions (hemangioma, angiokeratoma): Red, maroon, or red-blue to black lacunae - Malignant melanoma: Asymmetry, multiple colors, atypical pigment network, blue-white veil, atypical vascular pattern, irregular streaks, irregular dots/globules, irregular blotches, regression structures - Basal cell carcinoma: Arborizing blood vessels, leaf-like areas, large blue-gray ovoid nests, blue-gray globules, spoke wheel-like structures, ulcers, and shiny white structures. - Keratinocytic premalignant and malignant tumors: strawberry pattern, glomerular vessel, keratin mass, irregular hairpin vessels, polymorphous vessels.
