Basal cell carcinoma (BCC) is the most common skin cancer. Eighty percent of BCC affect the facial skin. The important challenge is removing all tumor cells to avoid recurrence because recurrent tumor is more difficult to cure. The current study describes the first surgically removed BCC of the concha and describes its management. A 65-year-old woman presented with left painless fixed conchal swelling proved by punch biopsy to be BCC. This mass was totally removed with 0.5 safety margin with excision of all the conchal cartilage and lower part of ascending ramus of the helix. Postauricular raw area was left to be healed with frequent dressing. Histopathological examination confirmed the diagnosis of BCC and proved free surgical margin. The patient was cosmetically satisfied and symptom free up to date without complication or recurrence. A case of BCC of the conchae was reported and could be safely and completely removed. This directs surgeon attention to BCC as a cause of conchal swelling as an early diagnosis when it is still small allows easy, safe removal without the need for reconstruction.

| Introduction|| |
Basal cell carcinoma (BCC) is by far the most prevalent skin cancer. Eighty percent of BCC affect the facial skin. The greatest challenge is removing all tumor cells to prevent a recurrence because recurrent tumor is more difficult to cure.
BCC usually grows only by local extension in both horizontal and vertical directions and can invade the deeper tissues, such as cartilage and bone. It rarely metastasizes, but it is malignant causing significant destruction and disfigurement by invading surrounding tissues. It is almost always curable when diagnosed and treated early.
| Case Report|| |
A 65-year-old female, homemaker, presented with painless swelling on the conchae of the right auricle that slowly increases in size over 2 years. Over the past 2 months, blood and pus oozed from the mass. She had no history of facial trauma or ear surgery. Apart from diabetes mellitus, she had no significant medical history. On clinical examination, hard, nontender nodular mass (2.5 cm × 2 cm) was detected on the right conchae with broad indurated base fixed to the conchal cartilage [Figure 1]. There were no other palpable masses in the head and neck region, and other otolaryngological examination was normal. General examination revealed no cutaneous or soft tissue tumors. Biopsy revealed BCC.

Computed tomography scan showed no deep extension to bone or external auditory canal with no reported neck lymph nodes. Routine preoperative laboratory tests were within normal limits.
After an informed consent form was signed by the patient, under general anesthesia, the mass was surgically removed with minimum 0.5 cm safety margin all around with complete excision of the conchal cartilage and excision of lower part of ascending ramus of the helix [Figure 2]. The wound was primarily closed around remaining auricular cartilage while postauricular exposed area on top of postauricular muscles was left to be healed with frequent dressing [Figure 1] and [Figure 2]. The postoperative course was uneventful and the patient was discharged at the same day of surgery without complaint.

A histological examination confirmed the diagnosis of BCC of solid type and proved free all surgical margins.
The patient was cosmetically satisfied and symptom free up to date without any complication. Moreover, a clinical examination revealed no recurrence or other pathologies [Figure 1].
| Discussion|| |
BCC is almost exclusively found in the head and neck with rare involvement of trunk and extremities. This tumor is commonly diagnosed on nose, eyelids, at the inner can thus of eyes, and behind the ears.
To the best of our knowledge, only one case was previously reported in the literatures up to date  in which Daoxian et al. described female patients had BCC that was diagnosed on conchae of the right ear and it was treated by LASER without reconstruction [Table 1].

We reported a case of proved conchal BCC. The current reported conchal BCC was histologically proved as conventional without a history of exposure to the risk factors of BCC. Unlike the previously reported case, as it was colorless, cauliflower in shape, much larger (about 2.5 cm × 2 cm), and has broad base fixed to the conchal cartilage [Table 1].
BCC of conchae is a common tumor in an uncommon location, where it is difficult to have an operation. The special location of BCC on the conchae often leads to misdiagnosis. Besides, it is difficult to perform surgery and apply suture on that anatomical area.
A 0.4 cm margin will excise BCC with a 95% 5-year cure rate provided the tumor is at low risk. The current case had low-risk criteria except that its size >2 cm. This was not a small BCC, but it was not giant BCC and did not invade surrounding structure. Hence, we did a surgical excision with at least 0.5 cm margins and achieved histologically free margins. It is said that Mohs micrographic surgery or excision with complete circumferential peripheral and deep margin assessment with frozen sections is recommended in high-risk and recurrent cases. We depended on permanent sections that more accurate. In addition, our case was not recurrent or giant BCC as its size <5 cm. Thus, we agree that radical surgical excision with microscopically tumor-free margins remains the treatment of choice for BCC because it is associated with a satisfactory disease-free survival, as previously reported.,
It is important to diagnose BCC when it is small in size before reaching large size enough to disturb nearby structures as external auditory canal, mastoid, and facial nerve that may make surgery more difficult and hazardous. While, when it is still small, it could be safely and completely resected.
To the best of our knowledge, this is the second case of BCC of the auricular conchae to be reported and the first conchal BCC that was surgically removed successfully. Therefore, BCC should be considered in the differential diagnosis of tumors of conchae, and cure could be achieved with excision with safety margins giving acceptable cosmetic result without reconstruction.
| Conclusion|| |
A case of BCC of the conchae was reported and could be safely and completely removed. This directs surgeon attention to BCC as a cause of conchal swelling as an early diagnosis when it is still small allows easy safe removal.
