Periungual basal cell carcinoma.

Periungual basal cell carcinoma is rare and needs to be differentiated from other common diseases that affect this region. Several factors are associated with the development of this tumor, and sun damage seems to play an important role in its pathogenesis. Dermoscopy of clinically indolent lesions on the nail unit can shorten the diagnostic process and avoid destructive treatment and functional damage.

Comparative Analysis of Clinical, Treatment, and Survival Characteristics of Basaloid and Squamous Cell Carcinoma of the Esophagus.

BACKGROUND: Basaloid squamous cell carcinoma (BSC) is a rare variant of squamous cell carcinoma (SqCC) of the esophagus. Even though pathologically thought to be more aggressive than SqCC, there is discrepancy in the literature regarding the outcomes of BSC compared with those of SqCC. STUDY DESIGN: We conducted a retrospective cohort study using the Surveillance Epidemiology and End Results (SEER) database. All patients with a histologic diagnosis of BSC and SqCC between 2004 and 2013 were included. We compared treatment and survival characteristics of patients with BSC and SqCC. RESULTS: There were 16,158 patients included in this study; 173 patients (1.1%) had BSC. There were no significant differences between the 2 groups based on age, sex, marital status, insurance, or geographic region of diagnosis, but patients with BSC were more likely to be Caucasian (73.4% vs 64.7%; p = 0.017). Among staged patients, baseline tumor stage was similar in both groups. However, BSC tumors were more likely to be of high pathologic grade (56.8% vs 38.2%; p < 0.001). Patients with SqCC were more likely to receive radiation therapy (36.9% vs 53.9%; p < 0.001), while patients with BSC were more likely to undergo resection (32.4% vs 17.0%; p < 0.001). Median overall survival was similar in both groups (14 vs 9 months; log rank = 0.144), and this relationship persisted after stratification by treatment. CONCLUSIONS: Even though more likely to be poorly differentiated at presentation, BSC of the esophagus seems to have similar clinical features and survival outcomes when compared with SqCC. Patients with BSC and SqCC should undergo stage-specific treatment to achieve optimal outcomes.

Collision of malignant neoplasms of the skin: basosquamous cell carcinoma associated with melanoma.

Collision tumors are characterized by the coexistence of two cancers in the same anatomical site and its pathogenesis remains controversial. Although uncommon, the association of basal cell carcinoma and melanocytic nevus is the most common among combinations of skin tumors. Even rarer is the association of two malignant tumors. We report a case of tumor collision representing melanoma and basosquamous cell carcinoma, a combination not previously described in the literature, since there are no reported cases of melanoma with this type of basal cell carcinoma.

The basaloid variant of squamous cell carcinoma of the larynx.

INTRODUCTION: Basaloid squamous cell carcinoma (BSCC) is a rare subtype of squamous cell carcinoma (SCC). Because of its rarity, both clinical and prognostic features of this variant are not well known. OBJECTIVE: In this study, we aimed to determine the frequency of BSCC and other SCC variants among all laryngeal SCC cases, and to determine clinical and prognostic features of BSCC variant. STUDY DESIGN: retrospective cohort study. Evidence level: Level 2b. MATERIAL AND METHODS: Records of the patients who had laryngeal SCC surgically treated at our institute between 2007 and 2013 were retrospectively reviewed. RESULTS: Among 198 subjects who had laryngeal SCC surgically treated, the frequency of the variants of SCC other than classical variant was 10.1% (20/198). The most common SCC variant was BSCC (6.6%). Eleven (84.6%) patients with BSCC were at an advanced stage at the presentation (p > 0.05). The 3-year overall survival and disease-free survival rates were 63% and 53% respectively. CONCLUSION: BSCC variant may be more common than previously reported. Since almost the half of patients experiences disease recurrence in the early period, multimodal treatment strategies should be employed at initial treatment, and a close follow-up is strongly recommended for this aggressive SCC variant.

INTRODUÇÃO: O carcinoma escamoso basaloide (CEB) é um raro subtipo do carcinoma de célula escamosa (CCE). Em decorrência de sua raridade, os aspectos clínicos e prognósticos dessa variante não são bem conhecidos. OBJETIVO: Determinar a frequência de CEB e de outras variantes do CCE entre todos os casos de CCE da laringe, assim como os aspectos clínicos e prognósticos da variante CEB. MÉTODOS: Trata-se de um estudo de coorte retrospectivo. Nível de evidência: 2b Os registros dos pacientes tratados cirurgicamente para CCE de laringe em nossa instituição entre 2007 e 2013 foram retrospectivamente revisados. RESULTADOS: Foram anotados 198 pacientes tratados cirurgicamente para CCE de laringe. A frequência das variantes de CCE diferentes da variante clássica foi 10,1% (20/198). A variante de CCE mais comum foi CEB (6,6%). Por ocasião da apresentação inicial, 11 (84,6%) pacientes com CEB estavam em estágio avançado (p > 0,05). Os percentuais de sobrevida geral após três anos e de sobrevida livre da doença foram 63% e 53%, respectivamente. CONCLUSÃO: A variante CEB pode ser mais comum do que o informado anteriormente. Considerando que praticamente metade dos pacientes sofre recorrência da doença em seu período inicial, devem ser introduzidas estratégias terapêuticas multimodais no tratamento inicial; além disso, recomendamos enfaticamente um cuidadoso seguimento para essa agressiva variante do CCE. .

Conclusão: O presente estudo confirma ascaracterísticas agressivas dos carcinomas basoescamosos, comoo tamanho maior e a elevada frequência de invasão perineural.Foi inesperado, no entanto, o achado de menor frequência nasáreas de alto risco.

Carcinoma basoescamoso: reporte de un caso con exposición crónica a arsénico ambiental / Basosquamous carcinoma: a case report with chronic environmental arsenic exposition

Basosquamous carcinoma is a relatively rare cutaneous tumour that shares some characteristics of both basal cell and squamous cell carcinoma. Currently most dermatologists consider that it represents a subtype of basal cell carcinoma with a more aggressive behaviour. The clinical presentation is non-specific and in general the diagnosis is made after the histopathological studies. The prevalence is higher in male patients, during the seventh decade and it tends to appear on sun exposed areas. Many authors compare its behaviour with squamous cell carcinoma. We present the case of a 44 years old male patient with a history of chronic arsenic exposure that presented a firm tumor in the left inguinal region and the biopsy showed basosquamous carcinoma with lymphatic involvement. This case shows an atypical presentation because of its localization and the appearance 20 years before the mean age reported in the literature. This could be explained by chronic environmental arsenic exposure, a well known risk factor for the development of cutaneous tumours.

El carcinoma basoescamoso es una neoplasia cutánea relativamente rara que reúne características de carcinoma basocelular y espinocelular. Actualmente la mayoría de los dermatólogos reconocen que este es un subtipo del carcinoma basocelular con comportamiento muchísimo más agresivo. Su presentación clínica es inespecífica y en general su diagnóstico se realiza sólo después de la biopsia. Predomina en pacientes de sexo masculino durante la séptima década de la vida y tiende a aparecer en regiones fotoexpuestas. Muchos autores igualan su comportamiento al del carcinoma espinocelular. Se presenta el caso de un paciente, de sexo masculino, de 44 años de edad, con antecedente de exposición a arsénico medioambiental crónica, que presentó aumento de volumen, duro en la región inguinal izquierda, cuya biopsia fue compatible con carcinoma basoescamoso con compromiso linfático. El caso de nuestro paciente muestra una presentación atípica por su localización y por la aparición 20 años antes de la media de edad reportada en la literatura. Esto podría ser explicado por la exposición crónica a arsénico, conocido factor de riesgo para carcinogénesis cutánea.

Carcinoma basoescamoso avançado de órbita: relato de caso / An advanced case of basosquamous carcinoma of the orbit: case report

Carcinoma basoescamoso é um tumor raro com características de tumor de células basais e escamosas interligados por uma área de transição. Tem sido descrito como um tumor agressivo com possibilidade de metástases à distância, o que difere substancialmente do carcinoma basocelular. Propomos neste relato a descrição de um caso de evolução crônica e das consequências do abandono do tratamento por causa do prognóstico reservado deste tipo de tumor de comportamento agressivo.

Basosquamous carcinoma is a rare tumor with features of both basal cell and squamous cell carcinoma, linked by a transition area. It is a rare epithelial neoplasm with a tendency for local recurrence. It also has a high incidence of distant metastasis, a condition that differentiates it from the basal cell carcinoma. In this case, the slow course of the infiltrative lesion associated to patient non-compliance to treatment led to a poor prognosis.

Carcinomas cutáneos: historia y clasificación / Cutaneous carcinomas: history and classification

Se efectua una apretada síntesis histórica desde los papiros egipcios hasta la actualidad. Luego se clasifica a los epiteliomas o carcinomas cutáneos en: 1- Carcinomas primitivos cutáneos. 2- Carcinomas intermediarios. 3- Carcinomas espinocelulares. 4- Carcinomas anexiales: sudoríparos, sebáceos, pilosos. 5- Carcinomas anexiales fundamentales. 6- Carcinomas "in situ" (intraepiteliales). Este sistema clasificatorio, basado en la histogénesis, ha demostrado ser de utilidad práctica a través del tiempo. Consideramos que se trata de un valioso trabajo de revisión y actualización producto de 5 décadas de experiencia. Se caracteriza por ser sintético, preciso y con criterio didáctico. Los conceptos están vertidos mediante 150 diapositivas demostrativas que expresan con certeza los caracteres clínicos e histológicos de las neoplasias cutáneas, salvo el melanoma. Uno de los autores (J.A) comienza el estudio en 1953 con su tesis de doctorado: "Epiteliomas cutáneos: ensayo de clasificación citogenética". Es un monumental ensayo ilustrado con numerosas microfotografías en blanco y negro, cuya consulta recomendamos en la Biblioteca de la Facultad de Ciencias Médicas de la UBA.

Histologic subtypes of oral squamous cell carcinoma: prognostic relevance.

Squamous cell carcinoma (SCC) is the most prevalent malignant neoplasm of the oral cavity. The conventional tumour and several histologic subtypes of SCC present morphologic features and specific behaviour when they occur in the oral mucosa. For example, basaloid SCC is an aggressive tumour and verrucous carcinoma has the lowest invasive and metastatic potential; however, the clinical and biologic course of these oral SCC variants has not been completely established. Furthermore, although numerous clinical and histologic features associated with oral SCC have been identified, none shows unequivocal prognostic significance. The purpose of this article is to review the various subtypes of oral SCC, emphasizing problems in their histologic diagnosis and prognosis.
