  • Clinicopathological Analysis of Cutaneous Angiosarcoma on the Scalp and Face in Elder Patients

    【摘要】 目的 探讨老年人头面部脉管肉瘤的临床病理学特征。 方法 1996年-2008年对5例老年人头面部脉管肉瘤的临床资料、病理形态学、免疫组织化学染色进行观察,并对其中4例进行了随访。 结果 临床表现主要是头面部发生的瘀斑、溃疡或结节状病变。肿瘤细胞围绕皮肤附件周围排列成交通状吻合的血窦网,衬覆有异型性的内皮细胞,有的区域内皮细胞形成乳头状突起。肿瘤组织内有不同程度的弥漫性出血。肿瘤细胞表达CD34、CD31、Fli-1和FⅧ,部分表达CD117和CK8/18。经随访3例3年内死亡,1例带瘤存活1年余,1例失访。 结论 老年人头面部脉管肉瘤组织形态多样,预后较差,及时诊治十分重要。需要与其他皮肤良性血管病变和低分化癌、恶性黑色素瘤、恶性梭形细胞肿瘤、Kaposi肉瘤等鉴别。【Abstract】 Objective To explore the clinicopathological features of cutaneous angiosarcoma on the scalp and face in elder patients. Methods The clinical data of five elder patients with cutaneous angiosarcoma on the scalp and face from 1996 to 2008 were retrospectively analyzed. The patients underwent the light microscopy, pathomorphological examination, and immunohistochemistry. Four patients were followed up. Results Most clinical manifestation was dusky irregular erythematous plaques which were often ulcerated. The tumor was composed of asymmetric collection of angulated and irregular vascular spaces infiltrating between collagen bundles. Endothelial cells attaching to the vascular spaces had hyperchromatic irregular nuclei and prominent nucleoli. Hemorrhage was another histologic feature. Positive expression of CD34,CD31,Fli-1 and FⅧ were found in tumor cells, and expression of CD117 and CK8/18 was found in some of the patients. In the follow-up duration, three patients died in three years, and one failed to be followed up. Conclusion Cutaneous angiosarcoma of the scalp and face has various histomorphology and poor prognosis, which should be diagnosed and treated in time. It should be distinguished from benign cutaneous hemangioma, poorly differentiated carcinoma, malignant melanoma and malignant spindle cell tumor.

    Objective To investigate and compare the effectiveness of perichondrial cutaneous graft (PCCG) of dorsal auricle for repairing defect after excision of melanocytic nevus in different parts of the face. Methods Between February 2008 and October 2012, 29 cases of facial melanocytic nevus were admitted. There were 11 males and 18 females, aged 3-25 years (median, 11 years). The locations were the upper eyelid in 5 cases, the nose in 15 cases, and the buccal region in 9 cases. The size of the nevi ranged from 1.2 cm × 1.0 cm to 4.0 cm × 2.2 cm. Defects after excision of nevi were repaired by PCCG of the dorsal auricle, which size ranged from 1.5 cm × 1.5 cm to 4.2 cm × 2.5 cm. The postoperative effectiveness was scored by patients according to color match, scar formation, and flatness of the reception site. The satisfaction evaluations were compared by the score among different parts. Results All the PCCG survived. All the patients were followed up 7-15 months (mean, 10 months). All the reception site had good color match and acceptable scar formation. The nasal part had good flatness, and the upper eyelid had poor flatness. Score comparison showed no significant difference in color match between 3 parts (P gt; 0.05). Nasal part had significantly less scar formation than buccal region and upper eyelid (P lt; 0.05), but no significant difference between buccal region and upper eyelid (P gt; 0.05). Nasal part and buccal region both had significantly better flatness than upper eyelid (P lt; 0.05), but no significant difference between nasal part and buccal region (P gt; 0.05). The overall evaluation score of nasal part and buccal region was significantly higher than that of the upper eyelid group (P lt; 0.05), and the score of the nasal part was significantly higher than that of the buccal region (P lt; 0.05). Conclusion PCCG of dorsal auricle has a good color match in repair of facial defect, especially in repair of nasal defect with good flatness and no obvious scar formation.

  • SUBMENTAL ISLAND FLAP FOR REPAIR OF ORAL DEFECTS AFTER RADICAL RESECTION OF EARLY-STAGE ORAL SQUAMOUS CELL CARCINOMA

    Objective To evaluate the effectiveness of the submental island flap for repair of oral defects after radical resection of early-stage oral squamous cell carcinoma (OSCC). Methods Between February 2010 and August 2011, 15 cases of early-stage OSCC were treated. Of 15 cases, 9 were male and 6 were female, aged from 48 to 71 years (mean, 63 years). The disease duration was 28-73 days (mean, 35 days). Primary lesions included tongue (3 cases), buccal mucosa (8 cases), retromolar area (2 cases), and floor of mouth mucosa (2 cases). According to TNM classification of International Union Against Cancer (UICC, 2002) of oral cancer and oropharyngeal cancer, 2 cases were classified as T1N0M0 and 13 cases as T2N0M0. The results of the pathologic type were high differentiated squamous cell carcinoma in 11 cases and moderately differentiated squamous cell carcinoma in 4 cases. The defect after resection of the lesion ranged from 5 cm × 3 cm to 8 cm × 6 cm. All the cases underwent radical resection of the primary lesion and immediate reconstruction with submental island flap except 1 case with radial forearm free flap because of no definite venous drainage. The sizes of the submental island flap varied from 6 cm × 4 cm to 9 cm × 6 cm. Results Operation time ranged from 4 hours and 30 minutes to 7 hours and 10 minutes (mean, 5 hours and 53 minutes) in 14 cases undergoing repair with submental island flap. All the flaps survived completely in 13 cases except 1 case having superficial necrosis of the flap, which was cured after conservative treatment. Temporary marginal mandibular nerve palsy occurred in 1 case, and was cured after 3 months; submandibular effusion was observed in 3 cases, and was cured after expectant treatment. The follow-up period ranged from 8 to 15 months (mean, 10.5 months) in 14 cases undergoing repair with submental island flap. Hair growth was seen on the flap and became sparse after 3 months in 2 male cases. The appearance of the face, opening mouth, swallowing, and speech were recovered well in 14 cases, and the donor site had no obvious scar. The follow-up period was 13 months in 1 case undergoing repair with radical free forearm flap, and the appearance and function were recovered well. No local recurrence was found during follow-up. Conclusion The submental island flap has reliable blood supply, and could be harvested simply and rapidly. It can be used to repair oral defects in patients with early-stage OSCC after radical resection.

  • APPLICATION OF FACIAL TISSUE EXPANDER FIBROUS ENVELOPE FOR TENSION REDUCTION

    Objective To investigate the application of the fibrous envelope of tissue expanders for the tension reduction. Methods Between June 2005 and May 2011, 21 patients with facial scar were treated with skin soft tissue expansion. There were 6 males and 15 females, aged 19-33 years (mean, 24.5 years), including 19 cases of hypertrophic scar and 2 cases of atrophic scar with disease duration of 1-31 years. The scars ranged from 4 cm × 2 cm to 25 cm × 10 cm. The tissue expander was implanted under normal skin adjacent to lesions in the first stage. And the post-expanded skin flap was designed as advance flap or transpositional flap as supplement in the second stage. Fibrous envelope at the base was fixed to the periosteum or fascia nearby first, and then sutures were used between envelopes at the base and on the skin flap or to the dermis of the skin flap to keep the mouth and lower eyelid in proper position. It reduced the tension of incision and maintained the contour of the face and neck. Results After the first stage operation, 2 cases had replaced expanders because of infection and leakage. No complication of infection or hematoma occurred after the second stage operation. The patients were followed up 1-18 months (mean, 10.2 months); of them,12 were followed up more than 1 year. No secondary deformity (deviation of mouth angle, eyebrows pulling, or eyelid ectropion) occurred. The flaps had good appearance and color. The satisfactory results were achieved. Conclusion In skin soft tissue expansion of the face, the fibrous envelopes at the base could reduce the tension of the incision and prevent the deformity of the mouth and lower eyelids.
