Aggressive and neglected basal cell carcinoma

Erosive rodent ulcer of the ear secondary to neglect

Basal cell carcinomas (BCCs) are slow-growing, locally invasive lesions that rarely metastasise, however, if left untreated can progress to extensive destruction of local structures giving rise to the alternative name 'the rodent ulcer'. Here we present a case of BCC of the ear progressing to destruction of the pinna and mastoid, involving the facial nerve and breaching dura. This case presentation shows not only the seldom-seen natural progression of the rodent ulcer with impressive imaging and clinical photographs but also highlights a broader topic of capacity and consent in patients displaying maladaptive denial or abnormal illness behaviour, how this can affect patient outcomes and what we as clinicians can do to ensure the best care for our patients.

Outcome of staged excision with pathologic margin control in high-risk basal cell carcinoma of the head region

Background

High-risk basal cell carcinoma involves a significant rate of basal cell carcinoma that requires Mohs micrographic surgery for definitive treatment. Staged excision with pathologic margin control is a simple, accessible, and curative procedure suggested for the treatment of high-risk basal cell carcinoma.

Objective

To evaluate the results of staged excision of high-risk basal cell carcinoma in the head region.

Methods

This interventional study was performed on patients with high-risk basal cell carcinoma, who underwent staged excision until the margins were free of tumor.

Results

A total of 122 patients (47 females and 75 males) with mean age of 57.66 ± 9.13 years were recruited in this study. Nasal and nodular types were the most common of both clinical and pathologic forms, respectively. Further, 89.3 % of cases were cured by staged excision after four years of follow-up. There was a significant relationship between treatment outcomes and recurrent lesions, multiplicity of risk factors, long-standing disease, and pathologic type. There was also a significant association between the number of surgical excisions and multiplicity of risk factors, as well as recurrence, location, and size of basal cell carcinoma.

Study limitations

Lack of magnetic resonance imaging assessment in cases of suspected perineural invasion.

Conclusions

High-risk basal cell carcinoma had a high cure rate by staged excision. Patients with more risk factors and those with nasal and recurrent basal cell carcinoma required more staged excisions. Failure of treatment is more probable in patients with more risk factors, long-standing lesions, and high-risk pathologic and recurrent basal cell carcinomas.

Management of high-risk and advanced basal cell carcinoma

Despite that basal cell carcinoma (BCC) is curative in the vast majority of cases, some patients are at high risk of recurrence and, in a few patients, lesions can progress to a point unsuitable for local therapy and prognosis is quite poor. The aim of the present work is to review clinical and pathologic characteristics as well as classical and new treatment options for high-risk, metastatic and locally advanced BCC. Surgery and radiotherapy remain the selected treatments for the majority of high-risk lesions. However, some patients are located on a blurry clinical boundary between high-risk and locally advanced BCC. Treatment of these patients is challenging and need an individualized and highly specialized approach. The treatment of locally advanced BCC, in which surgery or radiotherapy is unfeasible, inappropriate or contraindicated, and metastatic BCC has changed with new Hedgehog pathway inhibitors of which vismodegib is the first drug approved by FDA and EMA.

The analysis of reasons for malignant skin tumors late diagnosis

Introduction:

Timely diagnosis is a prerequisite for the successful treatment of malignant skin tumors. Late diagnosis leads a patient into a situation of losing valuable time and chance for cure.

Material and methods:

A prospective study was conducted from February 2006 until August 2011 which analyzed the reasons that led to establishing the diagnosis of malignant skin tumors in 220 patients. Patients were divided into two groups: Group A (102 patients), patients with diagnosed melanoma, and group B (118 patients) of patients suffering from basocellular (BCC) and planocellular cell (PCC) skin cancer. Parameters for comparison of analysis results were the reasons for coming to examination and reasons for not coming to the examination, because of which skin cancers were not diagnosed in time.

Goal:

To determine the factors that influences the establishment of late diagnosis and treatment of skin tumors.

Results:

It was confirmed that the prejudices of patients that tumors of the skin „should not be operated because it is dangerous“ is the main reason for late diagnosis. At the same time it is confirmed that the belief that it is unnecessary to operate congenital changes of the skin is the second most important reason for delayed diagnosis of malignant skin tumors.

Neglected Basal cell carcinomas in the 21st century

Although tumors on the surface of the skin are considered to be easily recognizable, neglected advanced skin neoplasms are encountered even in the 21st century. There can be numerous causes of the delay in the diagnosis: fear of the diagnosis and the treatment, becoming accustomed to a slowly growing tumor, old age, a low social milieu, and an inadequate hygienic culture are among the factors leading some people not to seek medical advice. The treatment of such advanced neoplasms is usually challenging. The therapy of neglected cases demands an individual multidisciplinary approach and teamwork. Basal cell carcinoma (BCC), the most common cutaneous tumor, usually develops in the elderly, grows slowly, and has an extremely low metastatic potential; these factors are suggesting that BCCs might well be the “ideal candidates” for neglected tumors. Five neglected advanced cases of BCC were diagnosed in our dermatological institute between 2000 and 2009. The clinical characteristics and treatment modalities of these neoplasms are discussed, together with the possible causes of the neglect.

Invasive giant basal cell carcinoma of the head: case report, reconstruction choice and literature review

It is unusual to find a giant invasive basal cell carcinoma in the occipital region of the head. We are presenting a case of basal cell carcinoma invading and eroding occipital bone, managed with an unusual scalp reconstruction method. A 69-year-old female presented with a 16x19 cm diameter tumour in the occipital region. Preoperative biopsy revealed a basal cell carcinoma. A complete surgical excision of the tumour was performed in one-step surgery and tissue defect was reconstructed by a pedicle latissimus dorsi musculocutaneous flap. Our case shows that this distant pedicle flap is safe and reliable, and should be revised as the option for the occipital region reconstruction.

Basal cell carcinoma with intracranial invasion

The risk of invasion and destruction of cranium, underlying dura, and cranial nerves by basal cell carcinoma (BCC) is extremely low, with an estimated incidence of 0.03%. Intracranial BCC invasion by direct extension is rare, and orbital spread from a nasal lesion has not been reported in the literature. We describe a case of intracranial invasion of a multiply recurrent nasal BCC, which caused progressive bilateral blindness from optic nerve compression, with spinal canal involvement causing subsequent lower extremity weakness and paralysis. This case underscores the importance of early and appropriate treatment of high risk BCC, and aggressive treatment of recurrent lesions as early as possible.
