The use of digital photography in the follow-up of surgical neoplastic wound : a case report

Introdução: As feridas oncológicas apresentam características peculiares, muitas vezes difíceis de expressar no texto escrito. A fotografia digital pode contribuir na descrição e na assistência destas feridas. Relato do Caso: Relatar o caso de paciente do sexo feminino, jovem, com lesão recidivada medindo 20x 18x13,7cm na coxa esquerda e diagnóstico de sarcoma sinovial. Utilizou-se a fotografia digital como facilitador na avaliação e tratamento de ferida oncológica complexa. A paciente foi submetida à exérese do tumor, curativos e enxertia de pele; o acompanhamento foi realizado com registros fotográficos com câmera do telefone celular, inserido no prontuário eletrônico e proporcionou a fotointerpretação pela equipe de saúde. Conclusão: O uso da fotografia foi importante, pois permitiu a avaliação rápida da ferida, pôde ser transmitida à equipe para avaliação do plano de tratamento e foram importantes ferramentas legais e para o ensino. ■ RESUMO

The photographic records were obtained using digital cameras of cell phones in the nursing team.The images were taken during dressing procedures, with the patient in the supine position, accommodated in a ward with ambient light.Data were analyzed and correlated to the number of media attached to the electronic patient record; clinical, photographic, and imaging conditions; scenario; and materials used for the assessment and analysis.Qualitative and quantitative data on the affected region, dimensions, appearance, solution of continuity, three-dimensional volume, and presence of necrosis and granulation tissues were obtained using the images.

CASE REPORT
A 31-year-old woman was admitted with a history of left thigh lesion 9 years ago.She has undergone two surgical procedures for tumor excision in another medical service, without confirmation of the diagnosis.She had recurrence and was admitted to our hospital.The physical examination revealed an infiltrative, expansive lesion measuring 20.0 × 18.3 cm on its larger dimensions (Figure 1).
The biopsy and histopathological examination showed a grade 3 biphasic synovial sarcoma classified by the Federation Nationale de Centers de Lutte Contre le Cancer, associated with immunohistochemical and cytogenetic study.Nuclear magnetic resonance imaging in the left thigh at admission (Figure 1) revealed an expansive lesion with aggressive features, and infiltrative appearance, affecting the anterior compartment muscles in the left thigh, with skin ulceration, and bulk tumor component through the cutaneous discontinuity area.The finding has a heterogeneous signal, which possibly delimits areas with hypersignal, probably secondary to necrosis.
No signs of bone involvement were found, the part of the non-compromised muscles was interposed between the femoral cortical and tumor lesion.Two satellite nodular lesions were found near the upper margin of the lesion, with similar signal characteristics.The lesion measured, in its largest diameters, 20.0 × 18.3 × 13.7 cm, and the satellite lesions measured 3.6 × 3.4 × 2.4 cm and 4.3 × 3.3 × 2.9 cm.Small lymph nodes were observed in the left inguinal region and were partially evaluated during the examination.
Computed tomography of the chest was normal.The patient underwent wide tumor excision in the left thigh.Follow-up was conducted with daily dressings, and reconstruction with partial skin graft was performed in the follow-up.
A digital photograph was taken upon admission, which serves as the baseline record of the image,

INTRODUCTION
A total of 600,000 new cancer cases are estimated to be diagnosed in 2018-2019 in Brazil 1 .Cancer formation results from the carcinogenic process, also known as oncogenesis, which is responsible for uncontrolled cell proliferation.A tumor only becomes visible after several stages, including loss of cutaneous integrity and infiltration of malignant cells into the skin structures, forming neoplastic wounds 2 .Among the predicted 600,000 new cancer cases, approximately 5-10% of patients will have tumor wounds, a more common condition in patients undergoing palliative care, which also increases due to primary tumors, secondary tumors, or recurring disease 3,4 .
Therefore, the team must treat these lesions appropriately to maintain patient comfort or, at least, minimize the discomfort resulting from this type of injury.Thus, these professionals seek to devise strategies that allow more accurate record of patient history, aiding in the development of an effective treatment plan 5,6 .
Therefore, technologies are commonly incorporated in patient care.Among them, digital photography is used for the documentation that facilitates recording the cicatricial evolution of the wounds.This practice positively facilitates proper communication among the team members, affecting the quality of care, providing support for the professional decision-making, and minimizing time and costs of treatment and patient suffering 7,8 .
In a systematic review on the methods used to evaluate wounds performed by Jørgensen et al. 9 , digital planimetry and imaging were considered the most accurate and reliable methods in measuring specific areas, especially large and irregular wounds.Until now, three-dimensional technologies have not yet been able to overcome this method due to their low accuracy, high cost, handling complexity, and difficult system interpretation.

OBJECTIVE
To report a case that used digital photography as a facilitator in the evaluation and treatment of a complex cancer wound

METHODS
This case report is conducted by evaluating the data extracted from an electronic medical record.Photographic records obtained during the treatment of a tumor wound between November 2017 and March 2018 were analyzed.The research was approved by the Research Ethics Committee of the Association of Social Pioneers, with identifying the cancer wound, such as the region affected, dimensions, appearance, skin continuity solution, three-dimensional volume, and presence of necrosis and granulation tissue (Chart 1).It also allowed correlation with clinical examination, magnetic resonance imaging, and histopathological examination, providing opportunities for all team members to evaluate the image at any time for descriptive and comparative analysis.Changes in the treatment plan should be guided during the follow-up or dressings (Figures 2-4).

DISCUSSION
Visual communication has been an important tool from the earliest days of human history, even before writing.We have tried to improve the communicating methods through imaging, allowing the observer to understand what they see, absorb the image, associate with their previous knowledge, and process it in order to draw their own conclusions.
The photo interpretation consisted of qualitative and quantitative data analysis of the photographic image considering the criteria presented in Chart 1 8 .The analysis of photographic records facilitated obtaining and evaluating the image, mainly because the object could not be touched and the wound was complex.The acquisition of images according to photographs has been used by plastic surgeons for a long time for pre-, trans-, and postoperative records 10 .
