RESUMO
Cutaneous basal cell carcinoma in situ is a recently proposed subtype of this skin cancer. It is characterized by either restriction of the tumor cells within the epidermis or the presence of tumor cells contiguous with the overlying epidermis that extend into the underlying dermis, or both. Importantly, cancer invasion-demonstrated by non-contiguous aggregates of basaloid tumor cells in the dermis-is not a feature of in situ basal cell carcinoma of the skin. A 63-year-old woman with cutaneous basal cell carcinoma in situ-superficial type that presented as an erythematous scaly plaque on her abdomen and a 61-year-old man with a cutaneous basal cell carcinoma in situ-fibroepithelioma type that presented as a flesh-colored smooth exophytic nodule on his back are reported. The characteristics of in situ basal cell carcinoma of the skin in these individuals are summarized. In conclusion, similar to other cutaneous malignant neoplasms-such as squamous cell carcinoma, malignant melanoma, and Merkel cell carcinoma-basal cell carcinoma of the skin can also present as an in situ cancer.

Bronchial fibroepithelial polyps are exceedingly rare with few cases have been reported. They can manifest with a wide array of symptoms; ranging from being totally asymptomatic, cough, refractory dyspnea, and hemoptysis. In our case, our patient's condition was diagnosed and was managed as asthma. It is one of the rare benign conditions to be encountered, shares similar morphology with other tumors such as angiomyofibroblastoma, aggressive angiomyxoma, and cellular angiofibroma. These lesions have a slow growth pattern which may end up with obstruction. According to the tumor size and symptoms caused by it, treatment varies from observation to complete resection. This case describes an incidental finding of fibroepithelial polyp in the main bronchus for a patient with long-term refractory cough for 5 years, was misdiagnosed to have asthma. Diagnosis typically involves imaging and bronchoscopy, followed by appropriate therapeutic measures and careful monitoring to assess the prognosis.

A 75-year-old Black man presented for evaluation of a skin lesion on his right shoulder. The lesion had been present for 3 months and was bleeding. A physical exam demonstrated a 2.7 cm exophytic, crusted, blue-to-purple plaque. A shave biopsy was performed, and histopathological examination revealed anastomosing strands of basaloid cells in the dermis, leading to a diagnosis of fibroepithelioma of pinkus (FeP). FeP is a rare variant of basal cell carcinoma. It typically presents as a solitary, pink, pedunculated papule on the lower back, but the presentation can vary. This case contributes to the scarce literature on the occurrence of FeP in skin of color populations. Here, we raise the possibility that FeP may present differently in skin of color patients compared to white patients. Greater clinician awareness can foster improved identification, management, and understanding of FeP in diverse populations.

We report the case of a young man who has never had any sexual contact presenting with a large scrotal lump with secondary bacterial infection. He reported no prior warts - genital or cutaneous. On examination, he had a large pink cauliform mass on the scrotum with four smaller but similar satellite lesions. Appearances were thought to be consistent with giant condyloma of Buschke and Lowenstein. Once superinfection was treated with oral antibiotics, he had a trial of imiquimod without success and was then referred to urology. After surgical excision, pathology concluded it was an inflamed fibroepithelial polyp with no malignant changes. To our knowledge, this is the first case report of a giant scrotal fibroepithelial polyp with characteristic gross warty features in an adult.

Fibroadenomas are the most common breast lesion in women of reproductive age. During pregnancy and lactation, fibroadenomas can undergo rapid growth in response to hormonal stimulus. These changes may prompt further investigation and/or intervention due to the risk of an underlying phyllodes tumour. We present a case of a female patient who underwent surgical excision of a giant fibroepithelial lesion at 4 months post partum while continuing to breastfeed. The lesion was successfully excised while maintaining lactation. A postoperative milk fistula resolved with non-operative management. There is limited literature on the surgical management of breast lesions in lactating women. This case illuminates the surgical management of breast lesions in an often well informed group of patients who may choose to have surgery while lactating in spite of the increased risk of complications. This case also highlights the need for a holistic approach to maintain the overall health of mother and child.

Vulval fibroepithelial polyps (FEPs) are a rare type of vulval fibroblastic tumour commonly found in premenopausal women. It is important to obtain an accurate pathological diagnosis because, despite being benign, the condition shares some characteristics with malignant vulva lesions in its differential diagnosis. We present a case of young woman in her 20s with a giant FEP. After surgical excision, the patient did not manifest any signs of recurrence after 1-year follow-up. Our review focuses on the distinguishing characteristics of these rare neoplasms as we explore their differential diagnosis.

Onychomatricoma is a rare, fibroepithelial tumor of the nail. Although it is benign, unnecessary and excessive treatment, such as extensive or total removal of the nail matrix, has been reported in the past. Recently, it was speculated that onychomatricoma is derived from onychomatricodermis, the dermal stroma of the nail matrix. Excision of the stromal rather than the epithelial component of the tumor is important. However, since the boundary between the normal and diseased stroma is usually unclear, minimal excision at the base of the tumor projection should be sufficient. We report a case of onychomatricoma and suggest a method of surgical treatment that would minimize postoperative deformity of the nail plate.

ABSTRACT Fibroepithelial polyps are benign non-epithelial tumors arising from mesodermal tissue and are commonly found on the skin. They can develop on the eyelid and surrounding area and rarely appear at other sites. While most cutaneous cases are diagnosed incidentally, the lesions may be symptomatic based on their location. The etiology of fibroepithelial polyps is not fully understood but may involve trauma, chronic irritation, allergic factors, and developmental or congenital causes. Although fibroepithelial polyps are benign lesions, they can be malignant in extremely rare cases. Herein we discuss 2 cases of fibroepithelial polyp with an atypical presentation and their treatment.
RESUMO Pólipos fibroepiteliais são tumores benignos não-epiteliais que surgem do tecido mesodérmico e são comumente encontrados na pele. Eles podem se desenvolver na pálpebra e na área adjacente, e raramente aparecem em outros locais. Embora a maioria dos casos cutâneos seja diagnosticada incidentalmente, as lesões podem ser sintomáticas com base em sua localização. A etiologia dos pólipos fibroepiteliais não é completamente compreendida, mas pode envolver trauma, irritação crônica, fatores alérgicos e causas de desenvolvimento ou congênitas. Apesar dos pólipos fibroepiteliais serem lesões benignas, podem ser malignos em casos extremamente raros. Aqui discutimos 2 casos de pólipo fibroepitelial com uma apresentação atípica e seu tratamento.

Abstract: Acquired fibrokeratoma is a rare benign skin tumor that usually manifests as a slow-growing solitary nodular lesion of the digits. We report a case of plantar acquired fibrokeratoma evidencing its atypical size and topography, in addition to the treatment with simple surgical excision followed by healing by second intention. Nondigital fibrokeratomas may occur in 18% of cases and rarely affect the palmoplantar region. These lesions are usually asymptomatic and show ≥ 3cm in size at the time of diagnosis due to delayed diagnosis. Complete surgical excision is the treatment of choice, which is usually curative. In general, primary closure is chosen; however healing by second intention becomes an option in regions of difficult approach.

La región vulvovaginal es una zona muy compleja por todos los elementos que la conforma y puede ser origen de un gran número de tumores benignos y en menor frecuencia de tumores malignos. En las últimas décadas, los tumores vulvovaginales han tenido un avance significativo en cuanto a su diagnóstico y tratamiento, dado por las aportaciones de la biología celular y molecular. El presente artículo pretende ser una referencia práctica para el diagnóstico clínico e histopatológico de estos tumores benignos así como en el tratamiento ambulatorio de algunos de ellos y su vigilancia.
The vulvovaginal region is a very complex area because of its anatomy and the fact that it can be source of a large number of benign tumors and less frequent malignant tumors. In recent decades, there have been significant gains in the diagnosis and treatment of vulvovaginal tumors, thanks to the contributions of cellular and molecular biology. The purpose of this review article is to serve as a practical reference for clinical and pathological diagnosis as well as in the outpatient treatment and monitoring of these benign tumors.

OBJETIVO: avaliar a taxa de concordância da biópsia percutânea com agulha grossa guiada por ultrassom seguida pela biópsia excisional em nódulos de mama palpáveis, sugestivos de tumores fibroepiteliais. MÉTODO: estudo retrospectivo que selecionou 70 biópsias com diagnóstico histológico de tumor fibroepitelial em 67 dentre 531 pacientes com lesões mamárias submetidas à biópsia percutânea com agulha grossa guiada por ultrassonografia, com transdutor linear de alta frequência (7.5 MHz), utilizando pistola automática Bard-Magnum e agulha 14 gauge. Foram incluídos os casos com diagnóstico de tumor fibroepitelial na biópsia percutânea ou biópsia excisional. Biópsias com diagnóstico histopatológico de fibroesclerose também foram incluídas no estudo. A força da concordância entre o resultado da biópsia percutânea e da biópsia excisional foi medida pelo coeficiente de Kappa. RESULTADOS: a biópsia excisional revelou 40 casos de fibroadenoma (57,1 por cento), 19 de tumor filoide (27,2 por cento) e 11 de fibroesclerose (15,7 por cento). A taxa de concordância para o fibroadenoma foi substancial (k = 0,68; IC95 por cento = 0,45 - 0,91), quase perfeita para o tumor filoide (k = 0,81; IC95 por cento = 0,57 - 1,0) e moderada para a fibroesclerose (k = 0,58; IC95 por cento = 0,36 - 0,90). CONCLUSÕES: a biópsia percutânea com agulha grossa é propedêutica minimamente invasiva que tem taxas de concordância com a biópsia excisional, de "substancial" a "quase perfeita". A fibroesclerose deve ser considerada no diagnóstico diferencial dos tumores fibroepiteliais.
PURPOSE: to evaluate the concordance rate of ultrasound-guided core needle biopsy followed by excisional biopsy in palpable breast lumps, suggestive of fibroepithelial tumors. METHOD: a retrospective study included 70 biopsies with a histological diagnosis of fibroepithelial tumor in 67 out of 531 patients with breast lesions submitted to ultrasound-guided core needle biopsy with a high frequency (7.5 MHz) linear transducer, using an automatic Bard-Magnum gun and a 14-gauge needle. Cases with a diagnosis of fibroepithelial tumor by core needle biopsy or excisional biopsy and with a diagnosis of fibrosclerosis were included in the study. The agreement between the two biopsy methods was assessed using the Kappa coefficient. RESULTS: excisional biopsy revealed 40 cases of fibroadenoma (57.1 percent), 19 cases of phyllodes tumor (27.2 percent), and 11 cases of fibrosclerosis (15.7 percent). The concordance rate for fibroadenoma was substantial (k = 0.68, 95 percentCI = 0.45 - 0.91), almost perfect for the phyllodes tumor (k = 0.81, 95 percentCI = 0.57 - 1.0), and moderate for fibrosclerosis (k = 0.58, 95 percentCI = 0.36 - 0.90). CONCLUSIONS: the core needle biopsy is a minimally invasive method that has "substantial" to "almost perfect" concordance rate with excisional biopsy. Fibrosclerosis should be considered in the differential diagnosis of fibroepithelial tumors.

El pólipo fibroepitelial es una lesión benigna de piel y mucosa genital y perineal. Se presenta en mujeres jóvenes, es poco frecuente e histológicamente muestra estroma laxo con prominentes y numerosas células atípicas, pleomórficas, multinucleadas. La lesión puede confundirse con rabdomiosarcoma botrioide, angiomixoma agresivo y neurofibroma mixoideo. Se revisaron los casos de nuestro archivo del período 1990-1996. Se recolectaron 13 casos, todas mujeres, cuya edad varió de recién nacido a 74 años. El tamaño de la lesión fluctuó de 0,3 a 2,5 cm; 12 lesiones únicas y 1 múltiple; localizaciones: vagina 6 (46,2 por ciento), ano 3 (23,1 por ciento), vulva 2 (15,4 por ciento) y uretra 1 (7,7 por ciento); en 1 caso la localización no se consignó. Histológicamente, las lesiones presentaban revestimiento escamoso normotípico, estroma, conjuntiva laxo, vascularizado, con moderada cantidad de células atípicas, pleomórficas, en partes formando rosetas, sin mitosis ni invasión del epitelio. Esta veriedad de papiloma es una lesión benigna, que simula sarcoma, que debe tenerse presente en el diagnóstico diferencial de sarcoma y pseudosarcoma de mucosa vaginal y piel perineal
