Jain AS, Duncan NB, Potter HD, Burkat CN, Warner EJ. A rare case of acantholytic squamous cell carcinoma presenting on non-sun exposed palpebral conjunctiva. Am J Ophthalmol Case Rep 2024; 35:102089. [PMID: 38975032 PMCID: PMC11225004 DOI: 10.1016/j.ajoc.2024.102089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Revised: 05/19/2024] [Accepted: 06/01/2024] [Indexed: 07/09/2024] Open
Abstract
Purpose This report describes the clinical and histological characteristics and management of a keratinized lesion of the palpebral conjunctiva in a 59-year-old male. The lesion was identified as a rare acantholytic variant of squamous cell carcinoma that atypically arose from a non-sun exposed region of palpebral conjunctiva. Management was complete excision via Mohs surgery. Observations A 59-year-old male presented with ocular irritation and chronic foreign body sensation in the right eye. Exam revealed a keratinized lesion in the right lower tarsal conjunctiva, and an initial shave biopsy was non-diagnostic. 12 months later, the patient presented with similar symptoms and a larger, more irregular lesion for which histopathology of a tarsal-involving excisional biopsy was consistent with acantholytic squamous cell carcinoma with involved margins. The patient subsequently underwent complete excision via Mohs surgery and a secondary reconstruction. Conclusions and importance Acantholytic variants of squamous cell carcinoma are rare and are described as arising from areas with routine sun exposure. This case reports such a lesion arising from non-sun exposed tarsal conjunctiva, as identified by histopathology of a full-thickness excisional biopsy. The lesion was successfully managed with complete excision via Mohs surgery and secondary reconstruction. Given that this histologic variant may be more aggressive and have higher rates of recurrence than other forms of squamous cell carcinoma, this case highlights the importance of complete excisional biopsy and accurate histopathology of concerning periocular lesions and offers a template for management of similar lesions. The unique presenting location should bring awareness to consideration of this type of malignancy developing on palpebral conjunctiva.

Abstract
Acantholytic squamous cell carcinoma is an infrequent subtype of squamous cell carcinoma. This tumour variant being rare in itself has been rarely described at the penile location, thus leading to a limitation on information of pathological and immunohistochemical findings and prognosis. Clinical observations indicate an aggressive biologic behaviour. The cytological features on fine-needle aspiration cytology samples have rarely been described in literature. It is imperative for pathologists to be aware of the cytological features so as to allow the distinction of this variant from conventional squamous carcinoma. Here, we explore an intriguing case of a metastatic tumour to inguinal lymph node with the primary lesion at the penis which constituted a diagnostic challenge on cytological examination.

Abstract
The most frequent cancer of the penis is the squamous cell carcinoma. Several variants of squamous cell carcinoma exist. It is important to make a difference between squamous cell carcinomas with and without a HPV infection. Furthermore, it is extremely important to recognize the different variants as their prognosis differs. These tumors are rare therefore classifying them can be challenging. This review is supposed to give an overview on the existing entities since 2016, but also allows a glimpse into the future with some comments on the upcoming WHO classification 2021.

Abstract
CONTEXT.— Lesions in the genitourinary (GU) organs, both benign and malignant, can demonstrate overlapping morphology, and practicing surgical pathologists should be aware of these potential pitfalls and consider a broad differential diagnosis for each specific type of lesion involving the GU organs. The following summary of the contents presented at the 6th Annual Chinese American Pathologists Association (CAPA) Diagnostic Course (October 10-11, 2020), supplemented with relevant literature review, exemplifies the common diagnostic challenges and pitfalls for mass lesions of the GU system of adults, including adrenal gland, with emphasis on immunohistochemical and molecular updates when relevant. OBJECTIVE.— To describe the common mass lesions in the GU system of adults, including adrenal gland, with emphasis on the diagnostic challenges and pitfalls that may arise in the pathologic assessment, and to highlight immunohistochemical workups and emerging molecular findings when relevant. DATA SOURCES.— The contents presented at the course and literature search comprise our data sources. CONCLUSIONS.— The diagnostic challenges and pitfalls that arise in the pathologic assessment of the mass lesions in the GU system of adults, including adrenal gland, are common. We summarize the contents presented at the course, supplemented with relevant literature review, and hope to provide a diagnostic framework to evaluate these lesions in routine clinical practice.

Abstract
BACKGROUND Acantholytic cutaneous squamous cell carcinomas (aCSCCs) have been classically considered as a high-risk variant of CSCC. However, more recent studies show that aCSCC does not confer more aggressiveness. This study aims to establish whether the prognosis of the aCSCC is worse than that of the non-acantholytic (naCSCC) or not. METHODS Retrospective case-control study with 50 aCSCCs and 50 naCSCCs. For each aCSCC, an naCSCC with similar high-risk features to the aCSCC but with no acantholysis was selected. Prognosis between both groups was compared. RESULTS The mean age was 86 years (SD 9.61). Sixty-one patients were men. Thirty-nine CSCCs were located in high-risk head and neck areas. Twenty CSCCs exhibited a poor degree of differentiation, and 36 showed an infiltrative growth pattern. The tumor diameter was 18.71 mm (interquartile range, IQR 35), and the tumor thickness was 6.72 mm (IQR 15.50). Twelve CSCCs exhibited perineural infiltration, and eight CSCCs exhibited invasion beyond the subcutaneous fat. Positive margins after excision of the tumor in 22 aCSCCs vs eight naCSCCs (P < 0.02). Nineteen poor-prognosis events were observed (local recurrence, lymph node metastasis, and death from CSCC). However, no differences were observed between both groups when comparing poor-prognosis events. CONCLUSION The proportion of unfavorable events is similar in aCSCC and naCSCC. The acantholytic histopathological subtype is not associated with a poorer prognosis than the non-acantholytic CSCC in our cohort.

Cancers (Basel) 2021; 13:cancers13030460.

Abstract
Simple Summary Penile cancer is an uncommon and understudied malignancy that is most commonly diagnosed in developing countries. Therapeutic advances have been slow, in part due to the lack of in vitro and in vivo models for testing new drugs before performing clinical trials. Recently, this difficulty has been partly overcome and multiple new pre-clinical models were reported. These important developments will help develop new therapies for penile cancer patients. The present review summarizes and discusses the available data concerning the pre-clinical models of penile cancer and their uses. Comparisons are drawn between different models, allowing researchers to choose the most adequate setting for their experiments. The remaining gaps in this array of penile cancer models are also discussed, in particular the lack of models for studying metastatic disease and cell lines representing tumors associated with human papillomavirus. Abstract Penile cancer is an uncommon malignancy that occurs most frequently in developing countries. Two pathways for penile carcinogenesis are currently recognized: one driven by human papillomavirus (HPV) infection and another HPV-independent route, associated with chronic inflammation. Progress on the clinical management of this disease has been slow, partly due to the lack of preclinical models for translational research. However, exciting recent developments are changing this landscape, with new in vitro and in vivo models becoming available. These include mouse models for HPV+ and HPV− penile cancer and multiple cell lines representing HPV− lesions. The present review addresses these new advances, summarizing available models, comparing their characteristics and potential uses and discussing areas that require further improvement. Recent breakthroughs achieved using these models are also discussed, particularly those developments pertaining to HPV-driven cancer. Two key aspects that still require improvement are the establishment of cell lines that can represent HPV+ penile carcinomas and the development of mouse models to study metastatic disease. Overall, the growing array of in vitro and in vivo models for penile cancer provides new and useful tools for researchers in the field and is expected to accelerate pre-clinical research on this disease.

Abstract
The majority of penile malignant tumors are squamous cell carcinomas. They are pathologically defined as epithelial neoplasms originating in the squamous cells of the inner mucosal lining of the glans, coronal sulcus or foreskin. Tumor location and site of origin is preferentially in glans (70%) followed by foreskin (25%) and coronal sulcus (5%). Despite the variable geographic distribution, pathological features of penile carcinomas in areas of high- and low-risk are similar. Penile tumors are morphologically heterogeneous. A major advance, based on biological, etiological and prognostic factors, is the 2016 WHO classification separating epithelial penile neoplasia, precancerous and invasive, in non-HPV and HPV-related.

Abstract
Acantholytic squamous cell carcinoma (acantholytic SCC) is a variant of SCC in which acantholysis develops owing to the loss of desmosomal adhesion proteins. This loss of cell-cell adhesion leads to morphologic changes that have the potential to mimic other tumor types, such as angiosarcoma or signet ring cell adenocarcinoma. Acantholytic SCC characteristically occurs in sun-exposed skin of elderly patients; however, it can occur in nondermal locations. We present a review of the literature describing cases of nondermal acantholytic SCC.

Abstract
The International Society of Urological Pathology (ISUP) held an expert-driven penile cancer conference in Boston in March 2015, which focused on the new World Health Organisation (WHO) classification of penile cancer: human papillomavirus (HPV)-related tumours and histological grading. The conference was preceded by an online survey of the ISUP members, and the results were used to initiate discussions. Because of the rarity of penile tumours, this was not a consensus but an expert-driven conference aimed at assisting pathologists who do not see these tumours on a regular basis. After a justification for the novel separation of penile squamous cell carcinomas into HPV-related and non-HPV-related-carcinomas, the histological classification of penile carcinoma was proposed; this system was also accepted subsequently by the WHO for subtyping of penile carcinomas (2016). A description of HPV-related neoplasms, which may be recognised by their histological features, was presented, and p16 was recommended as a surrogate indicator of HPV. A three-tier grading system was recommended for penile squamous carcinomas; this was also adopted by the WHO (2016). Many of the distinctive histological subtypes of squamous cell carcinoma of the penis are associated with distinct grades, based on the squamous cell carcinoma subtype histological features.

Abstract
Herein is described a unique case of esophageal cancer mimicking acantholytic squamous cell carcinoma (SCC). The patient succumbed to the disease within one month of diagnosis. Autopsy revealed a 10-cm esophageal tumor, characterized by prominent acantholysis-like areas composed of discohesive cancer cells, along with nested growth of SCC. These discohesive cancer cells focally exhibited pagetoid extension into adjacent esophageal epithelium, comprised ~60% of the esophageal tumor volume and had widely metastasized to the lungs, chest wall, liver, spleen, right adrenal gland, bones and lymph nodes. No metastases of SCC were observed. SCC cells were immunohistochemically positive for keratin 5/6 and E-cadherin and were negative for mucin and carcinoembryonic antigen (CEA). However, the discohesive cancer cells exhibited negativity for keratin 5/6, positivity for mucin and CEA, and diminished or no immunostaining for E-cadherin. Thus, these discohesive cells represented true adenocarcinomatous differentiation rather than acantholytic SCC cells. It was concluded that this tumor was an esophageal adenosquamous carcinoma with 'pseudo'-acantholytic adenocarcinoma components, which should be considered as a rare but distinctive type of aggressive cancer.

Abstract
Cutaneous squamous cell carcinoma is the second most common form of nonmelanoma skin cancer after basal cell carcinoma and accounts for the majority of nonmelanoma skin cancer-related deaths. In 2017, the American Joint Committee on Cancer revised the staging guidelines of cutaneous squamous cell carcinoma to reflect recent evidence concerning high-risk clinicopathologic features. This update reviews the literature on prognostic features and staging, including the eighth edition of the American Joint Committee on Cancer Staging Manual. A wide range of histopathologic variants of cutaneous squamous cell carcinoma exists, several of which are associated with aggressive behavior. A review of cutaneous squamous cell carcinoma variants, emphasizing diagnostic pitfalls, immuhistochemical findings and prognostic significance, is included. Of note, the eighth edition of the American Joint Committee on Cancer Staging Manual refers to squamous cell carcinoma of the head and neck only.

Abstract
Penile carcinoma (PC) is more frequent in underdeveloped countries, generally is diagnosed at an advanced stage when therapeutic options are restricted, and thus is associated with high morbidity/mortality rates. Recent studies have demonstrated clinical benefits with epidermal growth factor receptor (EGFR)-targeted therapy in patients with PC, although there is no test that provides accurate patient selection. The aim of the present study was to evaluate the prognostic value of EGFR gene and protein status in tumor samples from patients with primary penile squamous cell carcinoma. We assessed the expression of wild-type and 2 mutant EGFR isoforms (delA746-E750 and mL858R) by immunohistochemistry in 139 samples, of which 49 were also evaluated for EGFR copy number by fluorescence in situ hybridization (FISH). Positive immunohistochemical staining of wild-type and mutant EGFR was evidenced by complete and strong membranous staining. For FISH analysis, cases were considered unaltered, polysomic, or amplified, as determined by signals of the EGFR gene and chromosome 7. An independent cohort of 107 PC samples was evaluated for mutations in EGFR, KRAS, and BRAF. Protein overexpression was noted in nearly half of the cases and was associated with cancer recurrence (P=.004) and perineural invasion (P=.005). Expression of the 2 mutated EGFR isoforms was not observed. The FISH status was not associated with protein expression. Altered FISH (polysomy and gene amplification) was an independent risk factor for dying of cancer. Only 1 patient of 107 presented KRAS mutations, and no mutations of EGFR or BRAF were observed.

Abstract
Glandular and pseudoglandular tumors of the penile skin are extremely uncommon and can present diagnostic challenges. Primary adenosquamous carcinoma of the penis is an extremely rare tumor, composed of distinct areas of malignant squamous and glandular cells, making it a diagnostically challenging entity. The World Health Organization (WHO) recognizes several subtypes of squamous cell carcinoma (SCC), each with its own distinctive pathologic appearance, clinical associations and prognosis. Among these variants is the exceedingly uncommon adenosquamous carcinoma (ASC), representing 1%-2% of all SCC of the penis. Recent large studies have interrogated the presence of human papillomavirus (HPV) in malignant penile tumors and have shown specific morphologic patterns and clinical presentations to associate with HPV status. However, given the rarity of the adenosquamous variant of SCC, it has largely been excluded from these studies. The glandular components of these lesions can present a confusing appearance, particularly when a large tumor is represented on a small biopsy. Here we describe a difficult histologic presentation of this rare tumor, with the first published characterization of the HPV status of this subtype. This case represents a distinctly unusual case of metastatic HPV-positive primary cutaneous adenosquamous carcinoma of the penis.

Abstract
UNLABELLED The fourth edition of the World Health Organization (WHO) classification of urogenital tumours (WHO "blue book"), published in 2016, contains significant revisions. These revisions were performed after consideration by a large international group of pathologists with special expertise in this area. A subgroup of these persons met at the WHO Consensus Conference in Zurich, Switzerland, in 2015 to finalize the revisions. This review summarizes the most significant differences between the newly published classification and the prior version for renal, penile, and testicular tumours. Newly recognized epithelial renal tumours are hereditary leiomyomatosis and renal cell carcinoma (RCC) syndrome-associated RCC, succinate dehydrogenase-deficient RCC, tubulocystic RCC, acquired cystic disease-associated RCC, and clear cell papillary RCC. The WHO/International Society of Urological Pathology renal tumour grading system was recommended, and the definition of renal papillary adenoma was modified. The new WHO classification of penile squamous cell carcinomas is based on the presence of human papillomavirus and defines histologic subtypes accordingly. Germ cell neoplasia in situ (GCNIS) of the testis is the WHO-recommended term for precursor lesions of invasive germ cell tumours, and testicular germ cell tumours are now separated into two fundamentally different groups: those derived from GCNIS and those unrelated to GCNIS. Spermatocytic seminoma has been designated as a spermatocytic tumour and placed within the group of non-GCNIS-related tumours in the 2016 WHO classification. PATIENT SUMMARY The 2016 World Health Organization (WHO) classification contains new renal tumour entities. The classification of penile squamous cell carcinomas is based on the presence of human papillomavirus. Germ cell neoplasia in situ of the testis is the WHO-recommended term for precursor lesions of invasive germ cell tumours.

Abstract
Penile carcinoma is a rare genitourinary malignancy in North America and Europe with highest rates recorded in South America, Africa and Asia. Recent classifications have refined the terminology used in classifying intraepithelial/in situ lesions and additionally newer entities have been recognised in the invasive category. While increasing recognition of a bimodal pathway of penile carcinogenesis has facilitated understanding and classification of these tumours, handling and subtyping of penile malignancies presents a challenge to the reporting pathologist, in part due to their rarity. This article reviews the terminology and classification of in situ and invasive carcinomas and their relationship to human papilloma virus status. In addition, associated non-neoplastic dermatological conditions of relevance and appropriate ancillary investigations will be addressed.

Abstract
We describe the fifth case of mucoepidermoid carcinoma. The patient had penile ulcer with bilateral inguinal and pelvic lymphadenopathy and underwent total penectomy. After antibiotic therapy, the patient began outpatient chemotherapy, but the treatment was discontinued due to his intolerance. The patient died due to infectious complications of the inguinal lymphatic fistula 7 months after the histological diagnosis. Notably, the periurethral area was involved in the anatomopathological evaluation of the excised penis. The penile mucoepidermoid carcinoma was aggressive and the perimeatal region was involved. This case helps demystify the origins and prognosis of this rare case. More reports documenting patient characteristics and their evolution with penile mucoepidermoid carcinoma are needed.

Abstract
The incidence of penile cancer varies from country to country, with the highest figures reported for countries in Africa, South America, and Asia and lowest in the United States and Europe. Causes of this variation are not clear, but they are thought to be related to human papillomavirus infection, smoking, lack of circumcision, chronic inflammation, and poor genital hygiene. Most penile tumors are squamous cell carcinomas, and a variegated spectrum of distinct morphologies is currently recognized. Each one of these subtypes has distinctive pathologic and clinical features. About half of penile carcinomas are usual squamous cell carcinomas, and the rest corresponds to verrucous, warty, basaloid, warty-basaloid, papillary, pseudohyperplastic, pseudoglandular, adenosquamous, sarcomatoid, and cuniculatum carcinomas. Previous studies have found a consistent association of tumor cell morphology and human papillomavirus presence in penile carcinomas. Those tumors composed of small- to intermediate-sized, basaloid ("blue") cells are often human papillomavirus positive, whereas human papillomavirus prevalence is lower in tumors showing large, keratinizing, maturing eosinophilic ("pink") cells. Human papillomavirus-related tumors affect younger patients, whereas human papillomavirus-unrelated tumors are seen in older patients with phimosis, lichen sclerosus, or squamous hyperplasia. This morphologic distinctiveness is also observed in penile intraepithelial neoplasia. The specific aim of this review is to provide a detailed discussion on the macroscopic and microscopic features of all major subtypes of penile cancer. We also discuss the role of pathologic features in the prognosis of penile cancer, the characteristics of penile precursor lesions, and the use of immunohistochemistry for the diagnosis of invasive and precursor lesions.

Abstract
Most primary malignant tumors of the penis are squamous cell carcinomas (SCC) of the usual type. In recent years several variants, each with distinctive clinicopathologic features, have been described. Pseudohyperplastic carcinoma and carcinoma cuniculatum are both low-grade, extremely well-differentiated SCC variants characterized by an indolent clinical course and good prognosis. The former, which may be confused with pseudoepitheliomatous hyperplasia, preferentially affects the inner foreskin mucosa of elderly men and the latter is a verruciform tumor with an endophytic, burrow-like pattern of growth. Pseudoglandular carcinoma (featuring solid tumor nests with extensive central acantholysis simulating glandular lumina) and clear cell carcinoma (human papillomavirus [HPV]-related tumors composed of periodic acid-Schiff positive clear cells) are aggressive tumors with a high incidence of inguinal nodal metastases. Papillary carcinomas are HPV-unrelated verruciform tumors composed of complex papillae with acanthosis, hyper- and parakeratosis, absence of koilocytes, irregular fibrovascular cores, and jagged tumor base. Finally, in warty-basaloid carcinomas areas of warty (condylomatous) and basaloid carcinomas coexist in the same tumor, either separated or intermingled, giving the tumor a variegated appearance. In this review special emphasis is given to the differential diagnosis of these special variants with a discussion of the possible implications for clinical management.

Abstract
Pulmonary pseudoangiosarcomatous squamous cell carcinoma (PSCC) is a rare aggressive variant of squamous cell carcinoma. Histopathologically, PSCC is characterized by interanastomosing cords and channels, lined by atypical cells, with spaces containing erythrocytes or floating tumour cells. PSCC mimics angiosarcoma, so careful attention should be paid to immunohistochemical differences. Two PSCC cases are described here: in a 79-year-old male, bronchoscopy revealed mucosal swelling and hypertrophy and an adrenal mass was found 1 month later; in a 76-year-old male, computed tomography revealed rib destruction due to a non-calcified soft-tissue tumour and, although the tumour resembled an angiosarcoma, endothelial markers were negative and cytokeratin and p63 markers were positive. Immunohistochemical analyses may be helpful in establishing an accurate diagnosis. PSCC had a progressive course in both patients, who died ≤ 3 months postdiagnosis.

Abstract
BACKGROUND Acantholytic squamous cell carcinoma (ASCC) is frequently considered to be a more-aggressive variant with worse prognosis than other squamous cell carcinoma (SCC) subtypes. OBJECTIVES To analyze the biologic behavior of ASCC. METHODS We conducted a literature search of articles in English plus a manual search of cited references and common dermatology textbooks. RESULTS We found no comprehensive study on the biologic behavior of ASCC. Published data are scant, anecdotal, and contradictory. Of the articles investigated, the recurrence and metastasis rates ranged from 6% to 10% and 2% to 43%, respectively. CONCLUSION Analysis of the published evidence does not support the assumption that ASCC is a more-aggressive tumor with higher potential for recurrence or metastasis. As with other SCC types, prognosis is more dependent on the characteristics of the host and the location, size, depth, differentiation, and previous treatment of tumors. The treatment and follow-up of patients with ASCC should be similar to those for other types of SCC. The authors have indicated no significant interest with commercial supporters.

Abstract
Background Acantholytic squamous cell carcinoma (ASCC) is an uncommon histopathologic variant of SCC, characterized by marked acantholysis, wherein the tumor cells demonstrate defective cohesion to one another in the cancer nest leading to a pseudoglandular or pseudovascular appearance. The most common site of ASCC is the sun-exposed areas of the skin. Sporadic cases of ASCC have also been reported in various mucosal membranes and organs but to our knowledge this is the first case of primary ASCC of the large bowel. Case presentation A 59-year-old woman underwent right hemicolectomy due to large tumor in cecum and initial part of the ascending colon. Microscopically, the tumor consisted of nests of focally keratinizing large, atypical, squamous epithelial cells. Approximately 70% of the tumor showed acantholytic changes and acantholysis was equally distributed through the entire tumor. Immunohistochemically tumor cells were diffusely positive for cytokeratin (CK) AE1/AE3 and focally positive for epithelial membrane antigen and syndecan 1. All other tested antibodies (CK7, CK 20, CK MNF116, E-cadherin, beta-catenin, p63, p16, CD31, CD34, CEA, estrogen, progesterone) showed negative reaction. Periodic acid Schiff and alcian blue staining showed no intracellular or extracellular mucinous material in the tumor. The diagnosis of acantholytic squamous cell carcinoma of the cecum was suspected and additional examination was recommended to exclude possibility of metastatic carcinoma. Extensive clinical examination which also included whole-body PET/CT scan showed no additional tumors. After the exclusion of possible metastatic disease the diagnosis of primary acantholytic squamous cell carcinoma of the cecum was confirmed. Six months after surgery the metastasis in small intestine and recurrence in the abdominal cavity at the site of surgery appeared and had the same morphological characteristic as the primary tumor in the cecum. Conclusion We report a unique case of ASCC arising in cecum and on this way expands the range of tumors originating in colon. Reports of more cases of colonic ASCC would possibly help to elucidate origin, clinical behavior and therapy of these tumors.

Abstract
PURPOSE We evaluated clinicopathological features and outcomes in patients with penile squamous cell carcinoma. MATERIALS AND METHODS We studied 333 patients with homogeneous surgical treatment, including circumcision in 4, local excision in 2, partial penectomy in 194 and total penectomy in 133. Of the patients 153 also underwent bilateral groin dissection. Followup was 8 to 453 months (average 100). RESULTS The usual type of squamous cell carcinoma was noted in 65% of cases. Higher histological grade, deeper anatomical infiltration, and vascular and perineural invasion were common findings in sarcomatoid, basaloid and adenosquamous carcinoma cases, correlating with a higher rate of nodal metastasis and mortality. These features were unusual in verrucous, papillary and warty carcinoma cases. Recurrence in 22% of cases was common for the sarcomatoid, basaloid and adenosquamous types but was not noted for verrucous carcinoma. Locoregional relapse was more common in cases of usual, mixed, papillary and warty carcinoma, and systemic relapse was typical in sarcomatoid and basaloid carcinoma cases. The overall metastasis rate was 24% and the 10-year survival rate was 82%. The highest mortality rate was observed within the first 3 years of followup. High grade tumors were more common in penectomy cases and carcinoma exclusive of the foreskin had a better prognosis. The nodal metastasis risk groups were low--verrucous, papillary and warty, intermediate--usual and mixed, and high risk--sarcomatoid, basaloid and adenosquamous. Mortality risk groups were low--mixed, papillary and warty, intermediate--usual and basaloid, and high risk--sarcomatoid. CONCLUSIONS These data should help clinicians to design therapeutic strategies and followup protocols.
