Recalcitrant verrucous lesion: verrucous hyperplasia or epithelioma cuniculatum (verrucous carcinoma)

A 37-year-old woman originally presented in May 2003 with a nonhealing, painless ulcer on the plantar surface of her right foot that had been slowly increasing in size for the previous 1.5 years. Two weeks before presentation, a biopsy of the lesion, performed at another institution, had indicated a probable verrucous carcinoma. After preoperative workup, the patient underwent resection of the lesion, with clear margins and full-thickness skin grafting. The final pathologic findings were not consistent with verrucous carcinoma. A recurrent lesion was noted during a follow-up visit, and a second biopsy revealed a hyperkeratotic papillomatous verrucous lesion, type unclassified. No viral particles were isolated in the random biopsy samples. This recurrent lesion was refractory to treatment with topical acyclovir. Subsequent treatments consisted of imiquimod and CO(2) laser ablation, which succeeded in reducing the lesion. Verrucous lesions can be frustrating, and the diagnosis of epithelioma cuniculatum can be difficult to prove. We report a case highly suggestive of but not definitively diagnosed as epithelioma cuniculatum and summarize the literature on this entity.     

CT引导下经皮穿刺活检对肺部疾病的诊断价值

目的探讨CT引导下经皮切割针肺活检在影像学上表现为肺占位性疾病诊断中的作用和应用范围。方法选择2008年11月—2011年11月安徽省阜阳市人民医院呼吸内科CT引导下经皮肺穿刺活检,胸部CT表现为占位性病例48例,回顾分析所有病例的病史、肿瘤标记物、气管镜、胸部CT及肺活检病理。结果男性33例,女性15例,年龄22-79岁,平均57岁。48例均穿刺活检成功,37例确诊为恶性肿瘤,其中鳞癌18例,有一例肺穿刺活检结果为浆细胞性肉芽肿,术后标本病理为中分化鳞状细胞癌,此例患者以术后病理结果统计;腺癌12例,包括1例细支气管肺泡癌,现称肺原位腺癌;小细胞癌4例;低分化非小细胞癌2例;转移癌1例,该病例原发为左侧肾脏;硬化性血管瘤1例;结核2例;机化性肺炎1例;真菌2例,但未区分出曲霉和隐球菌;炎性假瘤1例;未确诊4例,穿刺结果为肺组织内较多炎性细胞浸润、增生的纤维组织或者坏死组织。术中或者术后发生气胸4例,咳血3例,肺部并发症14.6%,明确诊断率91.7%。结论 CT引导下经皮肺穿刺活检对肺部占位性疾病确诊率高,并发症少,具有重要临床应用价值。但对于特发性间质性肺炎诊断价值有限,为减少假阴性率,对CT引导下经皮肺活检不能明确诊断但可见较多炎性细胞浸润、增生的纤维组织或者坏死组织者,需结合临床及其他辅助检查,综合诊断。

Subungual squamous cell carcinoma masquerading as a melanotic macule

Subungual squamous cell carcinoma is a rare condition. Diagnosis is often delayed because it presents with minimal nail changes and mimics a number of benign nail conditions. We report a 43-year-old Chinese man who presented with a three-year history of an indolent melanotic macule of the fingernail. Histology from a punch biopsy revealed a well-differentiated squamous cell carcinoma. Wide local excision with full thickness skin grafting was performed. Physicians should have a high index of clinical suspicion as early nail biopsy and prompt tumour clearance can preserve joint function.     

Squamous cell carcinoma of the skin. Accuracy of clinical diagnosis and outcome of follow-up in Australia

The accuracy of the clinical diagnosis of 1292 non-melanotic skin tumours that were submitted to a private pathology service in 1980-1981 was determined. The clinical diagnosis that was written on the pathology slip which was submitted with the tumour was correlated with the histological diagnosis and the type of medical practitioner submitting the lesion. The clinical diagnosis was most accurate in the case of basal cell carcinoma; dermatologists most often reached this diagnosis correctly. For squamous cell carcinoma, although most frequently the lesions were diagnosed correctly clinically by dermatologists, their clinical diagnosis was confirmed in only 51% of cases. On average, 36% of squamous cell carcinomas were diagnosed clinically as basal cell carcinomas. The clinical course of 299 patients with a total of 305 squamous cell carcinomas that were selected from the squamous cell carcinomas that were submitted in 1980-1981 was traced. Four tumours (1.6%) which occurred in sun-exposed areas of the body metastasized, and 18 (7.5%) recurred locally. We conclude that those non-melanotic skin tumours which have the most potential to metastasize (squamous cell carcinomas) are those which are most poorly diagnosed clinically. It is recommended that patients with non-melanotic skin cancers should undergo biopsy as a routine to confirm the clinical diagnosis. Those who have a squamous cell carcinoma removed should be followed up for at least two years after the initial treatment.     

Squamous cell carcinoma of the breast following silicone injection of the breasts

During the 1960s, injecting liquid silicone into the breasts for augmentation purposes was a common practice. Many women suffered complications, usually developing silicone mastopathy, but there have been reports of carcinoma as well. A case of squamous cell carcinoma of the breast is reported in a patient who had previously undergone injection of silicone into the breasts. Upon review of the literature, this is only the second reported case of squamous cell carcinoma of the breast following silicone injection. Squamous cell carcinoma of the breast is a very rare tumor comprising 0.04 to 0.075 percent of all breast malignancies. The tumor appears to develop from metaplasia of benign epithelial cells within the breast. Many theories are presented for the development of this metaplastic process. The clinical presentation, evaluation, and treatment of squamous cell carcinoma of the breast is quite similar to that of infiltrating ductal carcinoma of the breast of comparable stage and size.     

Squamous cell carcinoma of the mastoid - a report of two cases

SummaryMalignant tumours of the mastoid are rare, the majority being squamous cell carcinomas. We report two cases whose clinical presentation mimicked mastoid abscess with intracranial complications. The first case is a twenty year Nigerian lady who presented to the Emergency Room of the Otorhinolaryngology Department with a one month history of headache, low grade fever, left facial palsy, neck stiffness and left post-auricular swelling on a background of left chronic suppurative otitis media since childhood. An initial diagnosis of meningitis and mastoid abscess secondary to chronic suppurative otitis media was made but histology of the mastoid specimen revealed keratinizing squamous cell carcinoma, which was treated with palliative primary radiotherapy. The second case is a 45-year old man with a chronic mastoiditis and mastoid abscess that was later found to be suamous cell carcinoma of the mastoid and was managed with combination of surgery and radiotherapy. The report highlights advanced stage of the disease at presentation, and discusses the etiology and management. To the best of our knowledge, these are the first cases of this entity to be documented in Africans.     

上消化道三原发早癌1例报道

Multiple primary malignant neoplasms (MPMNs) are rarely reported and it is important to give early diagnosis and proper therapy for these patients. Here reported a case of 62-year-old man with concomitant three early stage cancer lesions in upper gastrointestinal tract, all of which were detected by endoscopy. The first one was an IIc-type lesion at angular part of stomach under endoscopy, which was histologically confirmed to be a mucosal well-differentiated adenocarcinoma. The patient underwent a standard radical gastrectomy for the lesion after the failure of endoscopic treatment. The other two neoplasms were observed during follow-up and were indicated as early stage lesions by synthesizing information from endoscopy, endoscopic ultrasonography, computed tomography and biopsy. One displayed as a hyperemic patch (3 cm×4 cm in size) located at the part of esophagus 27 cm away from the incisor teeth and was proved to be moderately differentiated squamous cancer by histopathological examination. The other was an IIc-type lesion (3.0 cm×3.5 cm in size) located at the part of esophagus 36 cm away from the incisor teeth, and the biopsy result showed a poorly differentiated squamous carcinoma. Both the two lesions were treated with radical radiation because the patient refused surgery management. No recurrence of former lesions or occurrence of novel lesions were observed during post-treatment follow-up, suggesting radical radiation might be effective for this patient.

     

Cheilitis glandularis progressing to squamous cell carcinoma in an hiv-infected patient: case report

Cheilitis glandularis (CG), is a rare inflammatory minor salivary gland disease affecting the lower lip. The hallmarks of which include progressive enlargement and eversion of the lower labial mucosa resulting in the obliteration of the mucosal-vermillion interface. A case is presented of a 47-year-old HIV-infected woman who initially manifested clinical features of CG with a typical histopathology picture of a non-specific sialadenitis while a second biopsy performed six months later revealed well differentiated squamous cell carcinoma (SCC). She is symptom free one year following excision and radiotherapy treatment.     

Primary squamous cell carcinoma of the breast: a case report

Primary squamous cell carcinoma of the breast is a rare entity. We treated a 55-year old woman who came to us with bleeding from the left breast tumor. The tumor was 7 x 8 x 10 cm in size with ulceration and surgical biopsy results showed it to be squamous cell carcinoma of the breast, while metastatic work-up findings ruled out other sources of primary tumor. She also complained of nausea and vomiting, and brain CT disclosed cerebellar metastasis. The metastatic brain tumor was surgically removed, however, the symptoms became gradually exacerbated. The patient died 67 days after admission.     

Squamous cell carcinoma of the hallux

This article reports on a case of malignant degeneration of a hallux nail bed ulcer of 30 years' duration. Histologically, this lesion was determined to be a squamous cell carcinoma, a type of lesion that is also known as Marjolin's ulcer. The diagnosis, histologic findings, and treatment of patients with cutaneous squamous cell carcinoma are discussed.     

Squamous cell carcinoma in untreated psoriasis: a case report

Skin cancer developing after treatment for psoriasis is seen more often than expected, however, there has been no report of cutaneous squamous cell carcinoma developing in a case of untreated psoriasis. Here, a case has been reported where an untreated psoriasis lesion progressed on to develop squamous cell carcinoma, with a brief review of literature.     

Adenosquamous carcinoma of oral cavity: a case report

An elderly man presented with a pair of soft tissue swelling, one on upper and another on lower gums, with chest pain and respiratory distress. Histopathological examination of the biopsied material showed features suggestive of adenosquamous carcinoma, but CT-guided fine needle aspiration cytology from lung mass showed evidence of non-keratinising squamous cell carcinoma. This histologic dissimilarity between primary and metastatic tumour is a characteristic feature of the lesion. Palliative radiation was given as the patient was unfit for surgery, but his condition deteriorated rapidly and treatment had to be withdrawn.     

Squamous cell carcinoma arising from an epidermal cyst.

There are few case reports in the English literature concerning malignant transformation of an epidermal cyst into squamous cell carcinoma. We report a case of squamous cell carcinoma arising from a 40-year epidermal cyst in the proximal left thigh of a 74-year-old man. The epidermal cyst had increased in size in the previous 3 years. The patient presented with a discharge from the lesion. Ultrasonography and magnetic resonance imaging of the lesion suggested malignancy. An intra-operative frozen section of an incisional biopsy of the lesion found it to be an epidermal cyst with suspected malignant change, so a marginal excision of the lesion was performed. Squamous cell carcinoma arising from the epidermal cyst was confirmed histologically. A wide excision was done in order to obtain an adequate resection margin. A computed tomographic scan of the thorax and abdomen found no evidence of metastases. No evidence of recurrence was noted in the latest follow-up, 2 years postoperatively.     

Jejunal perforation secondary to metastatic bronchogenic carcinoma.

A case of peritonitis secondary to the perforation of a bronchogenic small bowel metastasis is reported. To our knowledge this is only the fourth case in which peritonitis was the presenting feature of a squamous cell carcinoma of the bronchus. The publications to date are reviewed and the need to biopsy every small bowel perforation found at laparotomy is stressed.

An unusual presentation of invasive squamous cell carcinoma of the upper extremities in a patient with a history of severe electrical burns and chronic thermal and chemical exposure

This is a case report that depicts an atypical presentation of very aggressive, metachronous invasive squamous cell carcinomas of the upper extremities in a patient with no prior history of precancerous or cancerous skin lesions and no significant solar radiation exposure. Potentially causative factors that played a role in the emergence of this aggressive form of skin cancer in this case study are multifactorial: (1) chronic thermal exposure of 3000 degrees F daily to his hands for an eight to ten-year time period; (2) chronic chemical exposure of DMSO solvent and higher levels of chemical contaminants such and finally; (3) a form of chronic immunosuppression as a result of his severe electrical burns that resulted in widespread second and third burns throughout his body.

Primary leiomyosarcoma of the penis: A rare penile neoplasm

Mesenchymal tumors arising in the penis are extremely uncommon. Sarcomas must be distinguished from sarcomatoid squamous carcinomas, owing to their treatment and prognostic implications. We report a rare case of leiomyosarcoma of the penis in a 70-year-old patient. Histopathology was of a high-grade spindle cell sarcoma, initially reported as sarcomatoid carcinoma on biopsy, subsequently confirmed on partial penectomy as a leiomyosarcoma.
