Ovarian Cystadenofibroma: An Innocent Tumor Causing Early Postoperative Small Bowel Obstruction and Perforation Peritonitis.

Ovarian serous cystadenofibroma (CAF) is a relatively uncommon variant of benign epithelial tumors of the ovary. It is frequently misdiagnosed as malignant ovarian mass, on both ultrasound (USG) and computed tomography (CT). Although most cases are easily treatable by surgery, some cases can present with life-threatening complications increasing patient morbidity and mortality. The present case report briefs about a 69-year-old female, P4 L4, who presented to the gynecology outpatient department with a complaint of pain in the lower abdomen for 2-3 months. USG and CT were suggestive of a suspicious-looking ovarian mass favoring malignancy. A staging laparotomy with pelvic and para-aortic lymphadenectomy with omental biopsy was done. Although the tumor was benign, extensive surgery, due to the suspicion of malignancy led to the patient developing early postoperative small bowel obstruction, mandating a re-exploration. CAF is a specific type of ovarian tumor that exhibits a combination of benign characteristics. This tumor presents as a partly cystic (containing fluid-filled sacs) and partly solid (composed of fibrous tissue) growth within the ovary, displaying a diverse architectural pattern. Mostly the diagnosis is incidental, on USG done for some other indication. CAF of the ovary needs a very high index of suspicion for diagnosis as these are frequently misdiagnosed as malignant ovarian masses. Although an innocent tumor, extensive surgery done for CAF, under suspicion for malignancy, can sometimes lead to serious complications.

Russell Body Cervicitis in a Human Immunodeficiency Virus-positive Female: An Unusual Presentation of Prolonged Cervical Inflammation.

Individuals living with HIV face an elevated susceptibility to various plasma cell disorders, encompassing a spectrum that spans from benign conditions like plasma cell chronic inflammation to more severe conditions such as aggressive multiple myeloma. The present case is one of the few cases of plasma cell rich inflammation of the cervix, and is probably the first being reported in an HIV positive female. A 34-year-old female, P2L2 with last child birth 8 years back visited gynecology OPD with complaints of copious vaginal discharge from last 1 year. The discharge was yellowish in color, non-foul smelling, watery in consistency and present all through the menstrual cycle. On per speculum examination, the cervix looked unhealthy and bleeding on contact was present. The Pap Smear was suggestive of a high grade squamous intra-epithelial lesion (HSIL). Biopsy revealed intense plasma cell-rich inflammation in the subepithelial stroma with Russel bodies. A summary of all reported cases of Russel cell cervicitis, reported till date and key points to differentiate it from other plasma cell rich cervical lesions like malakoplakia and plasmacytoma are also presented.

Isolated Papillary Thyroid Carcinoma of the Pyramidal Lobe: A Case Report and Review of Literature.

The pyramidal lobe (PL) represents an embryological remnant of the thyroglossal duct. A solitary focus of papillary thyroid carcinoma (PTC) of the PL of thyroid gland is a rare entity. We present a case of a 33-year-old woman with PTC of the PL with lymph nodal involvement and further discuss the lines of surgical management for primary PTC arising from the PL of thyroid gland.

Stratified Mucin-Producing Intraepithelial Lesion of the Cervix in an HPV- 16 Positive Woman: A Rare Encounter.

BACKGROUND: Cervical cancer is the fourth most common cancer among women globally and has a strong association with Human Papillomavirus (HPV) infection. Stratified mucinproducing intraepithelial lesion (SMILE), a variant of Adenocarcinoma in situ (AIS), is a rare cervical precancer lesion that is often missed or detected incidentally. CASE PRESENTATION: The present case report briefs the finding of a 39-year-old woman who presented to the gynecological outpatient department with complaints of vaginal discharge for 6-8 months. She had no history of irregular menstrual cycles or postcoital bleeding. Her routine Pap smear revealed atypical squamous cells of undetermined significance (ASCUS) and was positive for HPV-16 type. Her cervical biopsy report revealed AIS and her histopathological report of hysterectomy revealed SMILE, a variant of AIS. DISCUSSION: The SMILE variant of AIS is a rare cervical precancerous lesion characterized by the morphological overlap of both squamous intraepithelial lesions and AIS. It is often difficult to diagnose on Pap smear and is commonly associated with high-risk HPV infections. The management of SMILE is the same as that for AIS, which is the excisional procedure followed by a hysterectomy if the margins are negative and depending on the fertility desires of the patient, followed by regular follow-up with HPV testing. CONCLUSION: SMILE is a rare variant of AIS, which is often missed on cytological screening of the cervix. It is commonly associated with high-risk types of HPV. Hence, incorporating HPV testing in the screening of cervical cancer is important and recommended to increase the overall sensitivity of screening for adenocarcinoma lesions.

Non-gestational choriocarcinoma: unraveling the similarities and distinctions from its gestational counterpart.

Choriocarcinoma is a highly vascular and invasive tumor of anaplastic trophoblast, predominantly made up of cytotrophoblasts and syncytiotrophoblasts without villi. Based on its origin, choriocarcinoma can be either gestational or non-gestational. Non-gestational choriocarcinoma can be of germ cell origin, or can be seen in association with a somatic high-grade malignancy. It is difficult to differentiate gestational from non-gestational choriocarcinoma, especially in the reproductive age group. It is important to distinguish between the two, for accurate staging and prognostication, deciding the primary treatment modality, (ie, surgery or chemotherapy), and tailoring follow-up timeframes after diagnosis. An extensive literature search was performed regarding all cases of non-gestational choriocarcinoma, published before March 2023. A note was made of whether the origin of choriocarcinoma was ascertained and how gestational choriocarcinoma was differentiated from non-gestational choriocarcinoma. The keywords used for literature search were "non-gestational choriocarcinoma", "primary choriocarcinoma", "ovarian choriocarcinoma", "ovarian germ cell tumors", or "choriocarcinomatous differentiation". This review aims to summarize the similarities and differences in the epidemiology, pathogenesis, clinical presentation, and management guidelines between gestational and non-gestational choriocarcinoma, which can form an important educational resource for clinicians and laboratory physicians dealing with such cases.

A Simplified Method of Manually Constructing Small Format Tissue Microarray for Use in Resource-Constrained Settings.

Background & Objective: Tissue microarray (TMA) is a method of harvesting small tissue cores from a number of donor paraffin tissue blocks and arraying them in a recipient paraffin block. It has numerous advantages and applications but is expensive. This study aimed to develop a simple yet efficient method of manual, small-format TMA block construction. Methods: Disposable skin punch biopsy needles were used to manually core out 4-mm cylinders from the archival donor blocks comprising tissue from 60 thyroidectomy specimens. These cores were oriented in the embedding cassette in accordance with the grid design. The molten wax was slowly dispensed and allowed to be set. Sectioning, mounting, and hematoxylin and eosin (H&E) staining were performed by a conventional method. Immunohistochemical studies, using HBME-1, CK19, and S100 antibodies, were also performed on these tissue array sections. Results: There was no core loss during processing. Technical issues like core tilt and floatation were easily tackled. Morphological identification, histological typing, and immunohistochemical analysis could be satisfactorily performed in these TMA sections. Donor blocks did not break after punching. Conclusion: This TMA construction method is simple, feasible, easily reproducible, and time-saving. It can serve as an excellent cost-effective alternative for resource-poor laboratories for carrying out immunohistochemical studies.

Spindle cell carcinoma of male breast: Report of a rare case.

ABSTRACT: We report a rare case of spindle cell carcinoma, a histological subtype of metaplastic breast carcinoma, in a 40-year-old male who presented with an ulcero-proliferative lump in the right breast. Fine-needle aspiration cytology of the lesion showed poorly cohesive clusters of pleomorphic spindle-shaped cells, suggestive of malignant spindle cell tumor. Right mastectomy along with ipsilateral lymph node dissection was performed. Microscopic evaluation revealed a neoplasm comprising interlacing fascicles of oval to spindled pleomorphic cells with brisk mitosis and areas of necrosis. There was no nodal metastasis. Immunohistochemistry revealed a triple-negative phenotype along with diffuse positivity for CK5/6, vimentin, and smooth muscle actin. p63, beta-catenin, and CD34 were negative. The patient subsequently received adjuvant chemotherapy with 5-fluorouracil, adriamycin, and cyclophosphamide regimen and was disease-free at 1-year follow-up.

Nevus Lipomatosus Cutaneous Superficialis: Clinicopathological Spectrum of Six Cases from an Indian Archipelago.

Nevus lipomatosus cutaneous superficialis (NLCS) is a rare cutaneous hamartomatous lesion, histopathologically characterized by the presence of ectopic dermal adipocytes. Herein, reported is the clinicopathological aspect of six cases of NLCS, consisting of three males and three females, with age at presentation ranging from 18 to 47 years and duration of lesion ranging from 2 to 18 years. Out of the six cases, five were of solitary NLCS, who presented with nodules or polypoidal masses of variable sizes and duration. The lone case of classical NLCS presented with multiple skin-coloured cerebriform nodules over the right lower back in zosteriform distribution. The commonest location was lower back and thigh. Histopathological examination revealed lobules of mature adipocytes in the papillary and/or reticular dermis in all cases, thereby establishing the diagnosis of NLCS. Additional microscopic features encountered were surface ulceration, focal myxoid degeneration, mild perivascular lymphocytic infiltrate and attenuation of adnexal structures.

Utility of horizontal and vertical sections of scalp biopsies in various forms of primary alopecias.

BACKGROUND: This study was performed to demonstrate the usefulness of horizontal and vertical sections of scalp biopsies in diagnosing various forms of primary alopecias and to highlight the importance of error-free grossing. MATERIALS AND METHODS: A retrospective analytical review of 228 scalp biopsies was done, noting down the diagnostic histopathological features evident in horizontal and vertical sections of each cases. The idealness of the sections, especially horizontal section, was also analyzed. RESULTS: Out of the 228 cases, 44 scalp biopsies were classified histologically as cicatricial alopecias and the remaining 162 as noncicatricial alopecia. 22 cases were inconclusive owing to erroneous grossing. We found horizontal sections to be more useful in cases of noncicatricial alopecias, whereas vertical sections proved superior in cicatricial alopecias. CONCLUSION: Combining both horizontally and vertically sectioned scalp biopsies maximizes the diagnostic yield. When a single biopsy is submitted, the choice between horizontal and vertical section should depend on clinical diagnosis/suspicion.

A Unique Presentation of Primary Intestinal MALT Lymphoma as Multiple Lymphomatous Polyposis.

Multiple lymphomatous polyposis is considered to be a rare condition, with most of the cases being extranodal counterpart of mantle cell lymphomas. We report a rare case of multiple lymphomatous polyposis of the gastrointestinal tract in which the patient presented with abdominal pain and bloody diarrhea. Computer tomography of the abdomen showed circumferential wall thickening with intramural mass involving caecum & ascending colon with enlarged pericolonic lymph nodes. The patient underwent right hemicolectomy. Immunohistologic findings were characteristic of MALT lymphoma. Microscopic examination of polypoidal masses and mesenteric lymph nodes revealed infiltration by pleomorphic, atypical lymphoid cells which were CD20 positive and negative for CD3, CD10, Cyclin D1. Lymphoepithelial lesions were also noted. Careful endoscopic evaluation and histopathological review along with an immunohistochemical panel is extremely useful for accurately diagnosing such cases and avoiding unnecessary surgery and inappropriate therapy.

Evaluation of Perifollicular Inflammation of Donor Area during Hair Transplantation in Androgenetic Alopecia and its Comparison with Controls.

BACKGROUND: Mild perifollicular inflammation is seen in both androgenetic alopecia (AGA) cases and normal controls, whereas moderate or dense inflammation with concentric layers of collagen, is seen in AGA cases but only in very few normal controls, and may lessen the response to topical minoxidil. Moderate or dense lymphocytic inflammation and perifollicular fibrosis have poor hair growth following transplantation. AIM: The purpose of the study is to evaluate the perifollicular lymphocytic inflammation and fibrosis in AGA patients during follicular unit hair transplantation (FUT) and its comparison in normal controls. MATERIALS AND METHODS: A total of 21 male patients with AGA and 7 matched controls participated in the study. Histopathological analysis of biopsy specimens from donor strip of patients during the hair transplantation and two 4 mm punch biopsies on controls were performed. Morphometric analysis was performed and perifollicular fibrosis was scored based on the width of the condensed collagen at the lower infundibulum and isthmus from 0 to 3. Perifollicular infiltrate was also scored 0-3 and a total score of 3 or more out of 6 was considered significant. RESULTS: Nearly 76% of AGA patients had perifollicular fibrosis more than 50 µm at ×200 magnification. Almost 33.33% patients had moderate/dense perifollicular lymphocytic infiltrate whereas none of the controls had it. Total score in AGA cases was significantly higher than controls (P = 0.012) using Chi-square test. Out of 21 patients, 13 had a score of 3 or more and were followed-up with monthly treatment with intralesional steroids using a dermaroller. CONCLUSION: Histopathological evaluation of the donor area is a must during hair transplantation to evaluate the extent of perifollicular inflammation and achieve better results by following it up with treatment directed to decrease the inflammation.
