[A Case of Locally Advanced Breast Cancer Treated with Modified Radical Mastectomy with Immediate Reconstruction Using a Tissue Expander after Endocrine Therapy].

We experienced a case of locally advanced breast cancer treated with modified radical mastectomy with immediate reconstruction using a tissue expander after endocrine therapy. A 64-year-old postmenopausal woman had a 50 mm tumor in her right breast with extensive reddening of the skin. She had axillary lymph node metastasis. Core needle biopsy showed invasive ductal carcinoma with positive hormone receptor (ER+, PgR+) and negative HER2 status. The patient was diagnosed with locally-advanced breast cancer (cT4bN1M0, stage ⅢB). She was treated with anastrozole at a dose of 1 mg per day. The tumor decreased in size gradually and became operable after 7 months of anastrozole monotherapy. She underwent modified radical mastectomy with immediate reconstruction using a tissue expander. The resected specimen was a 30 mm tumor; adverse effects due to endocrine therapy were of Grade 1a severity. Seven months after adjuvant chemotherapy (FEC→DTX), the tissue expander was removed, and the right breast was reconstructed using an implant. No complications were noted, and the patient was treated with radiation therapy. Ten months have passed since surgery, and no local recurrence or distant metastasis has been noted.

A hybrid therapy for Buerger's disease using distal bypass and a free temporoparietal fascial flap: a case report.

Buerger's disease presents a difficult challenge, with its uncertain etiology and lack of a standardized therapy, and is often refractory to treatment. In the present report, we have described the case of a 43-year-old male with Buerger's disease, a refractory ulcer on his right great toe, and severe pain at rest. We obtained favorable results using a hybrid therapy that combined distal bypass with a free temporoparietal fascial flap. Postoperatively, the flap healed, and the patient's pain resolved. After more than 3 years of follow-up, he had had no recurrence of the foot ulceration, and the patency of the bypass graft had been confirmed using Doppler flowmetry. We believe that the hybrid therapy we devised for the present patient (ie, combined distal bypass with a free temporoparietal fascial flap) is an effective treatment of Buerger's disease with pedal ulceration. The therapeutic strategies for this condition should not adhere to a single treatment modality; rather, they should combine available treatment modalities according to each individual patient's condition.

CD9-positive Exosomes Derived from Cancer-associated Fibroblasts Might Inhibit the Proliferation of Malignant Melanoma Cells.

BACKGROUND/AIM: Exosomes secreted by various cells in the tumour microenvironment have been reported to be mediators of intercellular communication that play an important role in cancer progression. In this study, we aimed to investigate the effects of exosomes derived from cancer-associated fibroblasts (CAFs) on the proliferation of malignant melanoma (MM) cells and evaluated their clinicopathological significance. MATERIALS AND METHODS: Three malignant melanoma cell lines, A375, MMAc, and COLO679, and three CAFs established from malignant melanomas at stages 1a, 2b, and 3b, were used. The expression of CD9, CD63, and CD81 in CAF-derived exosomes was examined using western blotting. The effect of exosomes on the proliferative potential of cancer cells was analysed using cell counting and MTT assays. The expression of CD9, CD63, and CD81 was also immunohistochemically analysed in 90 malignant melanoma specimens. RESULTS: CAF-derived exosomes were positive for CD9 and CD63 and remarkably inhibited the proliferative capacity of A375 and MMAc cells. The five-year disease-free survival was significantly better in patients with CAF-derived CD9-positive exosomes than in CD9-negative patients. CONCLUSION: CAF-derived exosomes, especially CD9-positive exosomes, have an inhibitory effect on the proliferation of malignant melanoma cells. These findings suggest that CD9 expression in CAFs is a promising prognostic marker for patients with malignant melanoma.

Intense pulsed light therapy for aberrant Mongolian spots.

BACKGROUND: Aberrant Mongolian spots (AMS) distal to the lumbosacral region are thought to be more likely to persist than typical sacral Mongolian spots. So far, Q-switched ruby laser (QSRL) has been the treatment of choice for AMS. Intense pulsed light (IPL) is obtained from flashlamp devices that emit wavelengths between 515 and 1200 nm. IPL has documented efficacy for the treatment of irregular pigmentation, telangiectasia, rough skin texture, rhytids, hair removal, and vascular lesions, with several filters being available that can be used to block shorter wavelengths from the skin. As far as we could determine, there have been no clinical and histological studies on the treatment of AMS with IPL. Accordingly, the aim of this study was to assess the clinical and histological efficacy of IPL for AMS. METHODS: Seven patients (4 males and 3 females) presenting from September 2008 to July 2009 were assessed. Their mean age was 2.0 years, ranging from 0 to 7 years. The IPL device used in this study was a Natulight (Lumenis Ltd., Tokyo, Japan). Photographs were taken of all patients with a high-resolution digital camera at baseline and 6 months after treatment. Skin biopsy specimens were taken from 1 patient (case 4) before, immediately after, and 6 months after treatment. RESULTS: According to the 7 family members of the patients, the outcome of IPL was graded as follows: excellent improvement in 1 (14%), good improvement in 4 (57%), and slight improvement in 2 (29%). All families would have liked to continue IPL treatment. Evaluation of the effect of treatment by a physician was less favorable, with excellent improvement in 1 (14%), good improvement in 2 (29%), and slight improvement in 4 (57%). Histopathologic examination of the pigmented region revealed the typical features of a Mongolian spot in the hematoxylin-eosin stained section. Immediately after IPL, there were no changes in the dermis. At 6 months after treatment, however, the number of melanocytes in the middle and upper dermis was obviously decreased. CONCLUSIONS: IPL is an effective method for the treatment of AMS.

A Dynamic Costal Cartilage Platform Promotes Ocular Prosthetic Excursion: Preliminary Report.

The quality of life of the face involves mainly its configuration, and it plays an important functional role in communication skills. Thus, having artificial eyes is extremely essential in maintaining the quality of life of patients who have lost their eyeballs. We will present the details of the technique, including tips and innovations for eye socket reconstruction using spherical costal cartilage implant, which leads to dynamic and aesthetic results. METHODS: There were 19 cases of eye socket reconstruction using costal cartilages from 2008 to 2020. The patient age range was 18-77 years old. There were 10 cases of anophthalmia and 9 cases of ocular phthisis. In our operative method, we created the costal cartilage implant by harvesting the sixth costal cartilage of the affected side. If extraocular muscle remained, we sutured each muscle to the cartilage. RESULTS: Our method made application of thin artificial eyes possible in all cases. Regarding postoperative complications, there were 1 case of postoperative infection and 1 case of vascular failure of temporoparietal fascial flap. Seventeen cases were wet socket, and 2 cases were dry socket. We had attained movement of the artificial eye in 15 cases. CONCLUSIONS: Eye socket reconstruction is considered one of the most challenging operations, and various postoperative complications appear in the long term. Costal cartilages are considered as the most suitable materials to create the base of artificial eyes.

Dynamic eye socket reconstruction after extensive resection of midfacial malignancies: preliminary results using temporalis transfer.

The functional and esthetic results of reconstructive surgery after extended total maxillectomy or extended orbital exenteration greatly depend on the quality of the orbital reconstruction. We developed dynamic eye socket reconstruction using temporalis transfer to achieve good orbital reconstruction, and examined the usefulness of our technique. Five patients (three men and two women, aged 44-72 years) who underwent extensive resection of midfacial malignancies were treated with dynamic eye socket reconstruction using temporalis transfer. In most cases, eye socket reconstruction was performed approximately 1 year after the initial surgery, and temporalis transfer was used after maturation of the eye socket. The follow-up period ranged from 16 to 120 months (average 63.8 months). Movement of the upper and lower eyelids was achieved in all cases, and definite creases at the lateral canthus were observed in two patients. A good shape in the reconstructed medial and lateral canthal areas was maintained in all patients. Our reconstruction technique is extremely effective in creating natural creases ('crow's feet') at the lateral canthus during smiling, enabling movement of the upper and lower eyelids, and maintaining a sharp palpebral morphology.

Dynamic eye socket reconstruction after extended total maxillectomy using temporalis transfer.

The functional and cosmetic results of the reconstructive surgery after extended total maxillectomy greatly depend on the quality of the orbital reconstruction. In order to achieve good orbital reconstruction, we developed the dynamic eye socket reconstruction using temporalis transfer. In this report, I will present the details of the technique, including tips and innovations for dynamic eye socket reconstruction.Two patients (2 males, aged 70 and 72 years old) who underwent extensive resection of midfacial tumours were treated with dynamic eye socket reconstruction using temporalis transfer. The follow up period was 16 and 102 months. No acute complications were observed. The movements of the upper/lower eyelids including crow's feet were observed and a good shape in the reconstructed medial/lateral canthal area was maintained in all patients.This procedure provides both the eyelids with movement and also a good shape in the reconstructed medial/lateral canthal region. Furthermore, it contributes to achieving satisfactory functional and cosmetic results in the orbital reconstruction.

Psycho-oncological aspect of surgery in palliative care: our satisfactory experience using a V-Y island flap.

CONCLUSIONS: Our reconstruction method using a V-Y island flap was minimally invasive and yielded a satisfactory esthetic result without impairing the patient's postoperative quality of life (QOL). OBJECTIVE: Malignant skin tumors of the head and neck often affect the patient's appearance and QOL. Therefore, surgery for terminally staged patients with malignant skin tumors may be a treatment of choice for surgeons in a palliative care team to improve and sustain the patient's QOL. METHODS: We describe our experience of surgical treatment of a large primary malignant skin tumor in the head performed as part of palliative care in a 38-year-old woman in the terminal stage. We developed a V-Y island flap that did not result in postoperative alopecia. RESULTS: After surgery, the patient did not have alopecia and her hair hid the scar. The patient and her family were greatly satisfied with the result. Although the surgery did not extend her life, it alleviated her depressed condition caused by the uncomfortable primary tumor.
