Keloid of Ears: Recurrence and Its Complications

In this case report, we present a male patient who arrived at the hospital for the first time at the age of 8 with giant keloids in both ears and diagnosed by the Dermatology and Plastic Surgery as having the “Disease of Jorge Lobo”, which is a fungal infection due to the story of the endemic characteristics. After the first surgical intervention, he received guidance from the team for keloids and left the hospital using elastic mesh and a request to change the place where he lived to reduce his contact with the fungi. Fourteen years later, the patient returned to the Plastic Surgery Service having even larger keloids in both ears, twice the size than the first time. We did the second surgical in-tervention to remove it, but with the patient’s commitment that he would correctly comply with the guidelines determined by the surgical team. After finishing all the steps and a post-operative for the case, we observed the satis-faction and the increase of the patient’s mood, happier and without the embarrassment of that physical defect.


Introduction
The pathophysiology of keloids shows an immunological reaction against sebaceous secretion in patients affected by the disorder, in the occurrence of these lesions. T lymphocytes are attracted to the site with sebaceous secretion, leading to increased collagen formation and greater proliferation of fibroblasts [1]. gen fibers are formed with nodules that increase in size and are distributed irregularly. The skin of a keloid lesion has a flattened epidermis, without hair, sebaceous and sweat glands [2].
Keloids are disorders of skin repair characterized by excessive accumulation of extracellular matrix produced by fibroblasts and occur when there is not a normal healing process. Studies have shown the increased expression of COXs in keloids, suggesting that the pharmacological block could be used in the treatment [3].
Keloids are a pseudotumor proliferation that extends beyond the edges of the initial wound. It is a smaller keloid, a slightly raised and itchy scar that extends over normal tissue. It is an important keloid, a large, elevated, painful scar that protrudes from normal tissue, developed on extensive surfaces, creating pending tumors [4].
Diagnosed by the patient, it does not require laboratory or imaging exams, and, in a biopsy, we usually observe an increase in collagen and elastic fibers [5]. It is mistaken for hypertrophic scarring due to its similarity in pathology. In this paper, we will report the case of an 8-year-old child [6], male, who had rough, hard, with pruritus, gigantic protruding tumors in both ears, and with an onset report after a sting of an unknown insect. He lived in an endemic area, pond type, humid, and contaminated by waste and with the presence of street animals. This type of keloid is described as the disease of Jorge Lobo [7], as a deep, chronic, granulomatous fungal infection originating from trauma and fungal implantation (paracoccidioides loboi et loboa loboi) in cutaneous and subcutaneous tissues with a keloid aspect ( Figure 1). It is also called Lacazione, a disease that could infect humans and animals, such as mycoses. First, we programmed to do Beta-therapy [8], use of compressive meshes, and monthly steroid infiltration (triamcinolone). Three months later ( Figure 2), we performed the surgical removal of the giant tumors in the ears, with the hope that if the patient did all the recommendations, the lesion would not recur. In addition to all social problems, the patient was bulling in the city where he lived ( Figure 3) [9]. We got free beta-therapy, knitwear, and had follow-up for 30 days until discharge ( Figure 4).
Years later, at the age of 22, the same patient returned to the Plastic Surgery Service of the HFSE in Rio de Janeiro, with his head covered by the T-shirt, covering the recurrent keloid in both ears. In this second intervention, we removed almost 1 kg of the operative piece ( Figure 5) [10]. The postoperative period was considered satisfactory and more energetic measures for the late postoperative period were passed on to the patient's sister, who promised the team to supervise closely and follow the medical guidelines.
All of our operated patients signed the informed consent form from the hospital and the medical team.

Case Report
Fourteen years after the first discharge, the patient returns to the hospital with a larger tumor and in the same places. During the physical examination, we found that the keloid of the right ear was smaller than in the left ear. During the second removal procedure, we removed 350 mg from the right ear and 650 mg from the left ear, the main piece was 36 cm long in the shape of a giant "earring" on the left ear ( Figure 6) [11]. To perform the surgical removal, we identified piece by piece of keloid, being very careful to leave the skin on both sides, for the end-to-end raffia with simple stitches, separated and using nylon 4.0. We respect the main anatomical accidents that a normal ear has to make it look as good as possible: Helix, shell, lobe, and tragus (Figure 7) [12]. Given the complexity of the surgery, we considered a few scars at the end of the reconstruction. The larger keloids were found on the edges of the helices of both ears (Figure 8) and the pieces were sent to the Pathology Service, which confirmed the "keloid for an undetermined cause" [13].
In the immediate postoperative period, on the day of surgery, we performed a Beta-therapy session with 700 rds, repeated for 7 days interspersed in each ear [14]. On the fifteenth day, we modeled the lead sheet, which was used for 7 days. On the thirtieth day (Figure 9), before discharge, we made an intradermal infiltration with triamcinolone 10 mg [15], and 1/10,000 saline solution on the edges of both ears. The team followed up the patient for six months, once a month, using elastic semi-compressive mesh and without signs of recurrence [16]. We lost contact with the patient one year after the second surgery due to the change in the city. Five years later, we received a call from the patient and we were happy to know that he was married, with a son, employed, and was not ashamed of the small scars left by the last surgical intervention, which is why we decided to make this publication. 1 st extirpation:

Discussion
The history of this patient with the disease of Jorge Lobo motivated the team to research more about its causes. Fungal infection to differentiate from a common keloid of the idiopathic cause or by racial problems. What attracted the most attention, in particular, was the volume of tumors and lobular shape without sequence. We also noticed the presence of a pruritus (itch) complaint in the lesions, which is very common in keloids found in other types of scars. Due to their irregular shapes, the lesions did not guide us to a technique of extirpation, We discussed the possibilities of pre-operative infiltration of triamcinolone or compressive. We opted for beta-therapy in seven sessions immediately after surgery, on the same day, as stipulated by the radiotherapy team. Even so, we prescribed the facial elastic mesh for 12 months, in two stages: 6 months using 24 hours and 6 months using only at night. We monitored the patient for 12 months until he moved to another state in Brazil. Many ideas were presented, but we opted for those we had at that time.
As surgeons, we have had few cases similar to this. There were no cases of keloid in the procedures for placement of earrings or ornaments.

Conclusion
During our medical career, this was the biggest keloid we found and we had no idea how we were going to give hope to the patient, nor how to return his anatomically more perfect appearance and with all his anatomical accidents. We
